+## Pre-Issue Checklist
+
+<!--
+  Please go through this checklist item by item and make sure you have successfully completed each of these steps.
+    - You must be on the LATEST version of Terra to receive any support. There is no support for older versions of Terra.
+    - Make sure that this is not a *specific* compatibility issue with another terrain generation mod.
+        Do not request *specific* compatibility with mods or plugins (e.g. "Compatibility with TechCraft v7").
+        That should be implemented in an addon, **not** in the main project.
+        *General* compatibility (e.g. "Ability to pull Vanilla/Modded features from parent biomes") will be considered in the main project.
+    - Make sure that there are no already existing issues open with your problem. If you open a duplicate, it will be closed as such.
+    - Make sure that it is actually Terra causing the issue, and not another mod/plugin.
+        You can do this by testing to see if you can recreate the issue without Terra installed.
+    - Make sure that this is not an issue with a specific Terra *pack* or Terra *addon*, and instead applies to all of Terra.
+    - Make sure that you attach a copy of the latest.log file.
+        Putting *just* the exception IS NOT ENOUGH. We need to be able to check that there wasn't anything else before that caused it.
+    - Make sure that you have filled out all the required information and given descriptions of everything.
+    
+    You must put an x in all the boxes you have completed. (Like this: [x])
+    
+    To make sure that your issue is rendered properly, you may check the "Preview" tab (below the title) to see a rendered version of it before you submit it.

+# Terra Community Code of Conduct
+
+# TL;DR
+
+Polyhedral Development is dedicated to providing a harassment-free experience
+for everyone, regardless of gender, gender identity and expression, preferred
+pronouns, sexual orientation, disability, physical appearance, age, race,
+religion, etc. We do not tolerate harassment of participants in any form.
+
+This code of conduct applies to all Terra community spaces, including the github
+discussions tab, our [community discord server](https://discord.gg/PXUEbbF),
+the [community subreddit](https://reddit.com/r/TerraGenerator), or any other
+Terra space, both online and off. Anyone in violation of this code, as
+determined by the applicable moderators, may be subject to verbal warning,
+expulsion from these spaces, or future events and activities for an undetermined
+amount of time.
+
+Some Terra community spaces may have additional rules in place, which will be
+made clearly available to all participants. Participants are responsible for
+knowing and abiding by these rules.
+
+# Longer version
+
+Polyhedral Development is dedicated to providing a harassment-free experience
+for everyone. We do not tolerate harassment of participants in any form.
+
+## When and How to Use These Guidelines
+
+This code of conduct applies to all Terra community spaces, both online and off.
+This applies to the github discussion tab, the
+[Polyhedral Development community discord server](https://discord.gg/PXUEbbF),
+and any other Terra community. In addition, we may choose to invoke them in
+instances of harassment outside the Terra communities, and we will punish the
+responsible individuals appropriately. We will not tolerate harassment in any
+form, even outside of Terra.
+
+Some Terra spaces may have additional rules in place, which will be made clearly
+available to participants. Participants are responsible for knowing and abiding
+by these rules, in addition to this code of conduct.
+
+## Expected Behavior
+
+The following behaviors are expected of all members of the Terra community:
+
+### Be Respectful
+
+Value each other's ideas, styles and viewpoints. We may not always agree, but
+disagreement is no excuse for poor manners. Be open to different possibilities
+and to being wrong. Be respectful in all interactions and communications,
+especially when debating the merits of different options. Be aware of your
+impact and how intense interactions may be affecting people. Be direct,
+constructive and positive. Take responsibility for your impact, and your
+mistakes – if someone says they have been harmed through your words or actions,
+listen carefully, apologize sincerely, and correct the behavior going forward.
+
+#### Be Prepared to Admit When You are Wrong
+
+Any member of the Terra community should always be open to new ideas and must
+always be open to the possibility of being wrong. Nobody can always be right,
+and we are only human; we are
+[fallible](https://www.merriam-webster.com/dictionary/fallible) by nature. It is
+okay to make mistakes, but we must be willing to admit when we make one.
+
+### Be Direct but Professional
+
+We are likely to have some discussions about if and when criticism is respectful
+and when it's not. We must be able to speak directly when we disagree and when
+we think we need to improve. We cannot withhold hard truths. Doing so
+respectfully is hard, doing so when others don't seem to be listening is harder,
+and hearing such comments when one is the recipient can be even harder still. We
+need to be honest and direct, as well as respectful.
+
+### Be Inclusive
+
+Seek diverse perspectives. Diversity of views and of people on teams powers
+innovation, even if it is not always comfortable. Encourage all voices. Help new
+perspectives be heard and listen actively. If you find yourself dominating a
+discussion, it is especially important to step back and encourage other voices
+to join in. Be aware of how much time is taken up by dominant members of the
+group. Provide alternative ways to contribute or participate when possible.
+
+Be inclusive of everyone in an interaction, respecting and facilitating people's
+participation whether they are:
+
+- Not native language speakers
+- Coming from a different culture
+- Using pronouns other than "he", "she", or "they"
+- Living in a different time zone
+- Facing other challenges to participate
+- Or anything else. Be respectful of *everyone* at *all times*.
+
+Think about how you might facilitate alternative ways to contribute or
+participate. If you find yourself dominating a discussion, step back. Make way
+for other voices and listen actively to them.
+
+### Understand Different Perspectives
+
+Our goal should not be to "win" every disagreement or argument. A more
+productive goal is to be open to ideas that make our own ideas better. Strive to
+be an example for inclusive thinking. "Winning" is when different perspectives
+make our work richer and stronger. That means, you must pay attention to all
+ideas proposed. Don't disregard one without giving it the attention it deserves.
+
+### Appreciate and Accommodate Our Similarities and Differences
+
+People come from many cultures and backgrounds. Cultural differences can
+encompass everything from official religious observances to personal habits to
+clothing. Be respectful of anyone with different cultural practices, attitudes
+and beliefs. Work to eliminate your own biases, prejudices and discriminatory
+practices. Think of others' needs from their point of view. Use preferred
+titles (including pronouns<sup>[\[1\]](#1)</sup>) and the appropriate tone of
+voice. Respect people's right to privacy and confidentiality. Be open to
+learning from and educating others as well as educating yourself; it is
+unrealistic to expect someone to know the cultural practices of every ethnic and
+cultural group. Therefore we must be ready to correct someone if they make a
+mistake, and must be ready ourselves to change and learn if we make a mistake.
+
+### Lead by Example
+
+By matching your actions with your words, you become a person others want to
+follow. Your actions influence others to behave and respond in ways that are
+valuable and appropriate for our organizational outcomes. Design your community
+and your work for inclusion. Hold yourself and others accountable for inclusive
+behaviors.
+
+## Behavior That Will Not Be Tolerated
+
+The following behaviors are considered to be unacceptable and will not be
+tolerated:
+
+### Violence and Threats of Violence
+
+Violence and threats of violence are not acceptable - online or offline. This
+includes incitement of violence toward any individual, including encouraging a
+person to commit self-harm, engage in self-harm, or put themselves in a negative
+position (e.g. one which can lead to an increase of depression, etc.).
+
+### Personal Attacks
+
+Conflicts will inevitably arise, but frustration should never turn into a
+personal attack. It is not okay to insult, demean or belittle others. Attacking
+someone for their opinions, beliefs and ideas is not acceptable. It is important
+to speak directly when we disagree and when we think we need to improve, but
+such discussions must be conducted respectfully and professionally, remaining
+focused on the issue at hand.
+
+### Derogatory Language
+
+Offensive, unwelcome, or hurtful comments related to:
+
+- Gender
+- Gender identity or expression
+- Preferred pronouns<sup>[\[1\]](#1)</sup>
+- Marital status
+- Sex
+- Sexual orientation or identity
+- Native language
+- Age
+- (Dis)ability
+- Mental illness
+- Neuro(a)typicality
+- Race and/or ethnicity
+- Physical appearance
+- A person's lifestyle choices or practices,
+- A person's physical condition
+- A person's mental condition
+- Socioeconomic status
+- Religion
+- Employment
+- Or anything really. Just don't be offensive towards people, insult them, or
+  make unwanted comments.
+
+is not acceptable. This includes deliberately referring to someone by a gender
+that they do not identify with, and/or questioning the legitimacy of an
+individual's gender identity. If you're unsure if a word is derogatory, don't
+use it. This also includes repeated subtle and/or indirect discrimination; when
+asked to stop, stop the behavior in question.
+
+### Unwelcome Sexual Attention or Physical Contact
+
+Unwelcome sexual attention or unwelcome physical contact is not acceptable. This
+includes sexualized comments, jokes or imagery in interactions, communications
+or presentation materials, as well as inappropriate touching, groping, or sexual
+advances. Additionally, touching a person without permission, including
+sensitive areas such as their hair, pregnant stomach, mobility device (
+wheelchair, scooter, etc) or tattoos is unacceptable. This includes physically
+blocking or intimidating another person. Physical contact or simulated physical
+contact (e.g. emojis like ":&#8203;kiss:", ":hug:", or ":kiss_mark:", textual
+descriptions like "\*hug\*", "\*backrub\*", or "\*kisses you\*", etc.) without
+affirmative consent or after a request to stop will not be accepted.
+
+### Sexual Behaviour Where it is Not Appropriate
+
+Uninvited or off-topic sexual images, text, or behaviour in spaces where they're
+not appropriate will not be accepted whatsoever. We are an open community, which
+means spaces must be appropriate for all ages, and everybody must feel
+comfortable. Discussion of sexual things, will be prohibited unless otherwise
+noted.
+
+### Discussion of Sensitive Topics
+
+Discussion of sensitive topics when asked to stop, or when not appropriate.
+Including, but not limited to:
+
+- Anything sexual
+- Gore
+- Suicide
+- Self harm
+- Anything related to death
+- Or really anything that someone may be sensitive about.
+
+shall not be tolerated. As a community for all ages and all kinds of people, we
+must cater to everyone, and must make sure everyone feels comfortable here.
+Repeatedly breaking someone else's boundaries will not be tolerated.
+
+### Disruptive Behavior
+
+Sustained disruption of events, forums, or meetings, online or otherwise,
+including talks and presentations, will not be tolerated. This includes:
+
+- 'Talking over', 'heckling', or otherwise disrupting speakers.
+- Making derogatory comments about someone else's choices, pushing people to do
+  something they do not wish to do, talking about their choices or personal
+  preferences to others, or pressuring them to do something they don't wish to -
+  physically or through jeering.
+- Behaviour that intentionally disrupts an event.
+- Otherwise influencing actions that may cause hostility in the session.
+
+### Influencing Unacceptable Behavior
+
+We will treat influencing or leading such activities the same way we treat the
+activities themselves, and thus the same consequences apply. To make someone do
+something bad is the same thing as if you were to do it yourself, and we will
+not tolerate it.
+
+### Stalking or Following
+
+Stalking or following in any form (offline or online) is unnacceptable. In
+addition, you may not take pictures or record video of others without their
+express permission or when asked to stop. Any individual may also request for
+you to delete all footage you have of them, even if you took it with their prior
+consent.
+
+### Publication of Personal Information
+
+The publication of personally identifying information (commonly known
+as "[doxxing](https://en.wikipedia.org/wiki/Doxing)") is directly prohibited.
+You may not publish information that someone wants to keep private, unless it is
+necessary to protect vulnerable people from intentional abuse. Addditionally,
+you may not deliberately "out" any aspect of a person's identity without their
+consent, this includes gender, pronouns, sexual identity, etc.
+
+Unless it pretains to a case of harassment, as outlined here, in which case some
+personally identifying information may need to be brought up in private with the
+appropriate moderation team to help aid our efforts in keeping the community
+safe.
+
+### Deliberate Misuse of Pronouns<sup>[\[1\]](#1)</sup> or Names
+
+As an inclusive community, we must respect everyone. That means respecting the
+pronouns or names they wish for us to use. Deliberate misgendering, misuse of
+preferred pronouns<sup>[\[1\]](#1)</sup>, or use of 'dead' or rejected names is
+not to be tolerated. (If someone
+*accidentally* uses the incorrect pronouns, gender, or name, politely ask them
+to use the correct pronouns/gender/name. But if they are to continue using the
+incorrect pronouns, gender, or name, then you should escalate and report them to
+us.)
+
+### Not Stopping After Multiple Requests
+
+If someone asks you to stop doing something, then you should stop. Continuing to
+do it may be considered harassment, and can lead you to be removed from our
+community.
+
+## Complains We May Ignore
+
+Additionally, Terra prioritizes marginalized people's safety over privileged
+people's comfort. We reserve the right to ignore complaints regarding:
+
+- Claims of discrimination against non-marginalized or oppressed groups (eg.
+  being 'superphobic', meaning to not support people who are
+  'superstraight', which is a dog whistle for transphobic groups, or being '
+  cisphobic' without large amounts of evidence, etc.), or claims of
+  discrimination with no evidence. (Basically, don't report 'cisphobia' to us,
+  because it doesn't exist. But if someone is mocking you or making fun of you
+  for being cis, and it is *really* getting out of hand, then do tell us.)
+- Reasonable communication of boundaries, such as "leave me alone," "go away,"
+  or "I'm not discussing this with you." (If someone is asking you to stop, that
+  is not reason for you to report them as harassing you.)
+- Communicating in a 'tone' you don't
+  find [congenial](https://www.thefreedictionary.com/congenial). (You may not
+  report someone for harassment for being 'annoyed with you' or 'talking sternly
+  to you')
+- Criticizing or calling out racist, sexist, discriminatory, or otherwise
+  oppressive behavior or assumptions. (You may not say that someone is harassing
+  you if they are telling you to stop discriminating against someone.)
+- Disagreements that do not qualify as harassment. If you have a simple
+  disagreement with someone, and they have not been discriminating to anyone, in
+  any form, then we will not take action against them. Two people are allowed to
+  disagree on things without it getting toxic.
+
+We may also additionally choose to enact punishment for submitting a complaint
+in bad-faith or without adequate justification, if we deem necessary; if you're
+submitting a complaint just to troll or to annoy people, we may choose to have
+you banned or removed from the community spaces. Don't waste our time.
+
+In order to protect volunteers from abuse and burnout, we reserve the right to
+reject any report we believe to have been made in bad faith or with misintent.
+Reports intended to silence legitimate criticism may be deleted without
+response.
+
+## Reporting
+
+Terra has a global moderation team which is currently comprised of the following
+members:
+
+- solonovamax
+    - discord: [@solonovamax#6983](https://discord.com/channels/@me/566146322273402881)*
+    - github: [@solonovamax](https://github.com/solonovamax)

+    - github: [@dfsek](https://github.com/dfsek)
+    - email: [dfsek@protonmail.com](mailto:dfsek@protonmail.com)
+- duplex (duplexsystem)
+    - discord: [@Duplex#0797](https://discord.com/channels/@me/356822848641171456)*
+    - github: [@duplexsystem](https://github.com/duplexsystem)
+    - email: [duplexsys@protonmail.com](mailto:duplexsys@protonmail.com)
+
+\* The preferred method of communication is through discord. Although we will
+still be responsive on the other platforms, we will be more responsive on
+discord.
+
+These are people you can contact for anything regarding this code of conduct.
+
+If you are being harassed by a member of the Terra community, or by someone in a
+Terra community space, notice that someone else is being harassed, or have any
+other concerns, please contact a moderator of the platform it occurred on, or
+someone on the global moderation team. If the person who is harassing you is on
+the global moderation team, they
+will [recuse](https://www.thefreedictionary.com/recuse) themselves from handling
+your incident. (Meaning: if you are reporting someone on the team, they will not
+be involved in the discussion.) We will respond within a reasonable time frame,
+but generally within about 1 day.
+
+This code of conduct applies to Terra community spaces, but if you are being
+harassed by a member of Terra *outside* our spaces, we still want to know about
+it as we may choose to take action within our community. We will take all
+good-faith reports seriously and will always attempt to handle them
+appropriately. This includes harassment outside our spaces and harassment that
+took place at any point in time. The moderation team reserves the right to
+exclude people from Terra communities based on their past behavior, including
+behavior outside Terra spaces and behavior towards people who are not in Terra.
+
+Note: although we only have the ability to moderate official community spaces,
+if you are being harassed by someone in a non-official community space, and the
+moderation team of that platform refuses to do anything to help you (or even if
+they *do* help you), then you should notify us so that we may take appropriate
+action.
+
+We will respect confidentiality requests for the purpose of protecting victims
+of abuse. At our discretion, we may publicly name a person which we have
+received harassment complaints about, or privately warn third parties about
+them, but only if we believe that doing so will increase the safety of Terra
+community members or the general public. We will not name harassment victims or
+reporters of harassment
+(assuming the report was made in good-faith) without their explicit consent; all
+reports will remain anonymous by default.
+
+## Consequences of Unacceptable Behavior
+
+Participants asked to stop any harassing behavior are expected to comply
+immediately. Whether or not you comply immediately, you may still face
+consequences for you actions, but if the harasser doesn't comply immediately
+then we may choose to take additional actions to protect the Terra community
+members or the individual being harassed.
+
+Violation of this code can result in being asked to leave an event or online
+space, either temporarily or for the duration of the event, or being banned from
+participation in spaces, or future events and activities in perpetuity. If a
+participant engages in harassing behavior, the global moderation team may take
+any action they deem appropriate, up to and including expulsion from all Terra
+community spaces and identification of the participant as a harasser to other
+Terra community members or the general public. Bad behavior from any community
+member, including those with decision-making authority, will not be tolerated.
+
+In addition, any participants who abuse the reporting process will be considered
+to be in violation of these guidelines and subject to consequences. False
+reporting, especially to retaliate or exclude, will not be accepted or
+tolerated.
+
+## Questions
+
+if you have further questions for anything not addressed here, you may open an
+issue on this github repo, or contact a member of the global moderation team.

+## Notes
+
+#### \[1\]
+
+You provide a set of pronouns that everyone is comfortable addressing you with.
+Although some people are comfortable
+using [neopronouns](https://www.mypronouns.org/neopronouns), not everyone is.
+Therefore, if you use neopronouns, you should have at *least*
+one set of more common pronouns (One of he/him, she/her, or they/them; it
+doesn't matter which one. Anyone who doesn't respect your basic pronouns will be
+removed from the community.) that people may use, should they so choose, as some
+people are not comfortable
+using [neopronouns](https://www.mypronouns.org/neopronouns). But if someone
+refuses to use your more common pronouns, you should report them to us.
+Additionally, you may not ask people to use unreasonable pronouns, such as '
+acab/acabself', 'that/bitch', 'ur/mom', or anything else that may be considered
+disrectful. Doing so will be considered mockery of individuals who use
+non-standard pronouns and is very disrespectful.

+## Getting Started
+
+### Your First Contribution
+
+Unsure where to begin contributing to Terra? You can start by looking through "
+beginner" and "help wanted" issues:
+
+- [Beginner issues](https://github.com/PolyhedralDev/Terra/labels/Note%3A%20Good%20First%20Issue)
+    - issues which should be friendly to anyone new to terra.
+- [Help wanted issues](https://github.com/PolyhedralDev/Terra/labels/Note%3A%20Help%20Wanted)
+    - issues which should be a bit more involved than "beginner" issues.
+
+New to github? Working on your first Pull Request? Check
+out [How to Contribute to an Open Source Project on GitHub](https://app.egghead.io/playlists/how-to-contribute-to-an-open-source-project-on-github)
+to get you up on your feet.
+
+At this point, you're ready to make your changes! Feel free to ask for help;
+everyone is a beginner at first!
+
+If a maintainer asks you to "rebase" your PR, they're saying that a lot of code
+has changed, and that you need to update your branch so it's easier to merge.
+
+### Reporting Bugs
+
+This section guides you through submitting a bug report for Terra. Following
+these guidelines helps maintainers and the community understand your report, and
+spend their time fixing the issue instead of understanding what you mean.
+
+Before creating bug reports, please
+check [this list](#before-submitting-a-bug-report) as you might find out that
+you don't need to create one. When you are creating a bug report,
+please [include as many details as possible](#how-do-i-submit-a-good-bug-report)
+.
+
+> **Note:** If you find a **Closed** issue that seems like it is the same thing
+> that you're experiencing, open a new issue and include a link to the original
+> issue in the body of your new one.
+
+#### Before Submitting A Bug Report
+
+- Join the [discord server](https://discord.dfsek.com) to help resolve simple
+  issues.
+- You must be on the LATEST version of Terra to receive any support. There is no
+  support for older versions of Terra.
+- Make sure that this is not a *specific* compatibility issue with another
+  terrain generation mod. Do not request *specific* compatibility with mods or
+  plugins (e.g. "Compatibility with TechCraft v7"). That should be implemented
+  in an addon, **not** in the platform project.
+  *General* compatibility (e.g. "Ability to pull Vanilla/Modded features from
+  parent biomes") will be considered in the platform project.
+- Search for
+  any [already existing issues](https://github.com/PolyhedralDev/Terra/issues?q=is%3Aissue+)
+  open with your problem. If you open a duplicate, it will be closed as such.
+- Make sure that it is actually Terra causing the issue, and not another
+  mod/plugin. You can do this by testing to see if you can recreate the issue
+  without Terra installed.
+- Double check that this is not an issue with a specific Terra *pack* or Terra *
+  addon*, and instead applies to all of Terra.
+- Include a copy of the latest.log file. Putting *just* the exception is not
+  enough. We need to be able to check that there wasn't anything else before
+  that caused it.
+- Be sure to fill out all the required information and give descriptions of
+  everything.
+
+#### How Do I Submit A (Good) Bug Report?
+
+Bugs are tracked as [GitHub issues](https://guides.github.com/features/issues/)
+. [Create an issue](https://github.com/PolyhedralDev/Terra/issues/new) and
+provide the prerequisite information by filling in the Bug Report template.
+
+Explain the problem and include additional details to help maintainers reproduce
+the problem:
+
+- **Use a clear and descriptive title** for the issue to identify the problem.
+- **Describe the exact steps which reproduce the problem** in as many details as
+  possible. When listing steps, **don't just say what you did, but explain how
+  you did it**.
+- **Provide specific examples to demonstrate the steps**.
+- **Describe the behavior you observed after following the steps** and point out
+  what exactly is the problem with that behavior.
+- **Explain which behavior you expected to see instead and why.**
+- **If the problem wasn't triggered by a specific action**, describe what you
+  were doing before the problem happened and share more information using the
+  guidelines below.
+
+Include details about your configuration and environment:
+
+- **Which version of Terra are you using?** You can get the exact version by
+  running `/te version`.
+- **What's the name and version of the platform you're using**? (eg. Spigot,
+  Fabric, Paper, etc.)
+- **Which external plugins or mods do you have installed?**
+- **Which Terra packs do you have installed?** You can get that list by
+  running `/te packs`.
+- **Which Terra addons do you have installed?** You can get that list by
+  running `/te addons`.
+
+### Suggesting Enhancements
+
+This section guides you through submitting an enhancement suggestion for Terra,
+including completely new features and minor improvements to existing
+functionality. Following these guidelines helps maintainers and the community
+understand your suggestion and find related suggestions.
+
+Before creating enhancement suggestions, please
+check [this list](#before-submitting-an-enhancement-suggestion) as you might
+find out that you don't need to create one. When you are creating an enhancement
+suggestion,
+please [include as many details as possible](#how-do-i-submit-a-good-enhancement-suggestion)
+.
+
+#### Before Submitting An Enhancement Suggestion
+
+- You must be on the **LATEST** version of Terra to make sure your feature
+  hasn't been added yet.
+- Search for
+  any [already existing issues](https://github.com/PolyhedralDev/Terra/issues?q=is%3Aissue+) (
+  Including closed!) with your problem. If you open a duplicate, it will be
+  closed as such.
+- Verify that this is actually within the scope of Terra.
+- Be sure that this is not a feature request that should be made for a specific
+  Terra *pack*, and instead applies to all of Terra.
+- Be sure that this is not something that should be implemented as a Terra
+  addon, and instead applies to all of Terra.
+- Make sure that you attach a copy of the latest.log file, if there are any
+  exceptions thrown in the console. Putting *just* the exception
+  **is not enough**. We need to be able to check that there wasn't anything else
+  before that caused it.
+
+#### How Do I Submit A (Good) Enhancement Suggestion?
+
+Enhancement suggestions are tracked
+as [GitHub issues](https://guides.github.com/features/issues/). Create an issue
+on our platform repository and provide the following information:
+
+- **Use a clear and descriptive title** for the issue to identify the
+  suggestion.
+- **Provide a step-by-step description of the suggested enhancement** in as many
+  details as possible.
+- **Provide specific examples to demonstrate the steps**.
+- **Describe the current behavior** and **explain which behavior you expected to
+  see instead** and why.
+- **Explain why this enhancement would be useful** to most Terra users and isn't
+  something that can or should be implemented as an addon.
+
+### Pull Requests

+
+## Styleguides
+
+### Git Commits
+
+Following this is not mandatory, but rather a set of guidelines. As long as your
+commit messages aren't absolutely awful, it's probably fine. But it would be
+nice if you followed them.
+
+#### Committing
+
+When you commit code, try to avoid committing large amounts of code in a single
+go. Splitting up code into smaller commits is much nicer and makes it easier to
+trace a feature to a single commit.
+
+Try to stick to one feature/fix/etc. per commit. A good rule of thumb is if you
+need to use the word "and" in the subject line, then it should probably™ be two
+commits.
+
+#### Git Commit Messages
+
+- Subject line must fit the following format: `<type>: <short summary>`. Type
+  must be one of the following:
+    - Build: Changes that affect the build system or external dependencies.
+    - Docs: Documentation only changes.
+    - Feat: A new feature.
+    - Fix: A bug fix.
+    - Perf: Performance improvements.
+    - Refactor: Refactoring sections of the codebase.
+    - Repo: Changes to the repository structure that do not affect code. (Eg.
+      modification of the `README.md` file, etc.)
+    - Revert: Revert a previous commit.
+    - Style: Code style updates.
+    - Test: Anything related to testing.
+    - Trans: Translation and localization of Terra to other languages.
+    - WIP: Work in progress.
+- Separate the subject line from the body with a single blank line.
+- Do not end subject line with a period.
+- Limit the subject line to 50 or less.
+- The subject line and all body lines should be in sentence case.
+- Use the present tense. ("Add feature" not "Added feature")
+- Use the imperative mood. ("Move cursor to..." not "Moves cursor to...")
+- Reference relevant issues and pull requests in the body.
+
+>
+> Here is a template you can follow:
+> ```
+> Capitalized, short (50 chars or less) summary
+>
+> More detailed explanatory text, if necessary. Wrap it to about 72
+> characters or so. In some contexts, the first line is treated as
+> the subject of the commit and the rest of the text as the body. The
+> blank line separating the summary from the body is critical (unless
+> you omit the body entirely); various tools like `log`, `shortlog` and
+> `rebase` can get confused if you run the two together.
+>
+> Explain the problem that this commit is solving. Focus on why you are
+> making this change as opposed to how (the code explains that). Are
+> there side effects or other unintuitive consequences of this
+> change? Here's the place to explain them.
+>
+>
+> Further paragraphs come after blank lines.
+> - Bullet points are okay, too
+> - Typically a hyphen or asterisk is used for the bullet, followed
+>   by a single space, with blank lines in between, but conventions vary
+>   here
+> - Use a hanging indent
+>
+> Reference any relevant issues at the bottom, like so:
+>
+> Resolves: #123
+> See also: #456, #789
+> ```
+
+### Code Styleguide
+
+Use an IDE with support for `.editorconfig` files. There is an included
+editorconfig file in the base of the project so that your IDE should
+automatically use the correct code style settings.

+
+## Coding Practices
+
+### Compatibility
+
+#### General Compatibility
+
+General compatibility (example: injection of Vanilla structures/features/carvers
+into packs) is acceptable in the platform project.
+
+- General compatibility features should be *disabled by default*. Having things
+  auto-injected causes unpredictable behaviour that is annoying to diagnose.
+  General-compatibility options should have config values attached which are
+  disabled by default.
+- These config options should also be *simple to use*. Think of the people who
+  will be using these compatibility options. They want to flick a switch and
+  have things be compatible. That means that a majority of compatibility options
+  should stay in `pack.yml`, to make it simple to go into a pack and turn on
+  specific compatibilities. This does *not* mean that more advanced
+  compatibility options are off the table, for example, look at Feature
+  compatibility, where features can either be automatically injected, *or*
+  configured individually per Terra biome, depending on how much control the
+  user wants.
+
+#### Specific Compatibility
+
+Specific compatibility should *not* be put in the platform project. (Example:
+Adding the ability to generate TechCraft v7's doo-dads with a TerraScript
+function)
+
+Having specific compatibilities leads to tons of extra dependencies to keep
+track of, as well as adding lots of additional stuff to maintain. It quickly
+becomes a mess. Especially when most users will never need to use this feature.
+
+We have designed an addon API for exactly this purpose. **Specific
+compatibilities are welcome and encouraged, in the form of addons.**
+
+### Platform-Agnostic Design
+
+Terra must, at all times, remain platform agnostic. This means it must be able
+to run on theoretically any voxel based platform. Including non-minecraft games
+like Terasology.
+
+When adding a new feature to `common`, make no assumptions about what platform
+it'll be running on.
+
+Examples:
+
+- Don't assume the world height is 256.
+- Don't assume that a specific block, item, or entity exists. (Eg. don't assume
+  there exists a block called `minecraft:grass_block`)
+
+### Data-Driven
+
+When adding a new feature, make it abstract. Don't make assumptions about "
+specific use cases." If you can only think of a few use cases, your idea should
+probably be generalized.
+
+You must use configs effectively. Make configs that are *powerful* but also *
+make sense* and are \[easy\] to use.

-                    GNU GENERAL PUBLIC LICENSE
-                       Version 3, 29 June 2007
-
- Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-                            Preamble
-
-  The GNU General Public License is a free, copyleft license for
-software and other kinds of works.
-
-  The licenses for most software and other practical works are designed
-to take away your freedom to share and change the works.  By contrast,
-the GNU General Public License is intended to guarantee your freedom to
-share and change all versions of a program--to make sure it remains free
-software for all its users.  We, the Free Software Foundation, use the
-GNU General Public License for most of our software; it applies also to
-any other work released this way by its authors.  You can apply it to
-your programs, too.
-
-  When we speak of free software, we are referring to freedom, not
-price.  Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-them if you wish), that you receive source code or can get it if you
-want it, that you can change the software or use pieces of it in new
-free programs, and that you know you can do these things.
-
-  To protect your rights, we need to prevent others from denying you
-these rights or asking you to surrender the rights.  Therefore, you have
-certain responsibilities if you distribute copies of the software, or if
-you modify it: responsibilities to respect the freedom of others.
-
-  For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must pass on to the recipients the same
-freedoms that you received.  You must make sure that they, too, receive
-or can get the source code.  And you must show them these terms so they
-know their rights.
-
-  Developers that use the GNU GPL protect your rights with two steps:
-(1) assert copyright on the software, and (2) offer you this License
-giving you legal permission to copy, distribute and/or modify it.
-
-  For the developers' and authors' protection, the GPL clearly explains
-that there is no warranty for this free software.  For both users' and
-authors' sake, the GPL requires that modified versions be marked as
-changed, so that their problems will not be attributed erroneously to
-authors of previous versions.
-
-  Some devices are designed to deny users access to install or run
-modified versions of the software inside them, although the manufacturer
-can do so.  This is fundamentally incompatible with the aim of
-protecting users' freedom to change the software.  The systematic
-pattern of such abuse occurs in the area of products for individuals to
-use, which is precisely where it is most unacceptable.  Therefore, we
-have designed this version of the GPL to prohibit the practice for those
-products.  If such problems arise substantially in other domains, we
-stand ready to extend this provision to those domains in future versions
-of the GPL, as needed to protect the freedom of users.
-
-  Finally, every program is threatened constantly by software patents.
-States should not allow patents to restrict development and use of
-software on general-purpose computers, but in those that do, we wish to
-avoid the special danger that patents applied to a free program could
-make it effectively proprietary.  To prevent this, the GPL assures that
-patents cannot be used to render the program non-free.
-
-  The precise terms and conditions for copying, distribution and
-modification follow.
-
-                       TERMS AND CONDITIONS
-
-  0. Definitions.
-
-  "This License" refers to version 3 of the GNU General Public License.
-
-  "Copyright" also means copyright-like laws that apply to other kinds of
-works, such as semiconductor masks.
-
-  "The Program" refers to any copyrightable work licensed under this
-License.  Each licensee is addressed as "you".  "Licensees" and
-"recipients" may be individuals or organizations.
-
-  To "modify" a work means to copy from or adapt all or part of the work
-in a fashion requiring copyright permission, other than the making of an
-exact copy.  The resulting work is called a "modified version" of the
-earlier work or a work "based on" the earlier work.
-
-  A "covered work" means either the unmodified Program or a work based
-on the Program.
-
-  To "propagate" a work means to do anything with it that, without
-permission, would make you directly or secondarily liable for
-infringement under applicable copyright law, except executing it on a
-computer or modifying a private copy.  Propagation includes copying,
-distribution (with or without modification), making available to the
-public, and in some countries other activities as well.
-
-  To "convey" a work means any kind of propagation that enables other
-parties to make or receive copies.  Mere interaction with a user through
-a computer network, with no transfer of a copy, is not conveying.
-
-  An interactive user interface displays "Appropriate Legal Notices"
-to the extent that it includes a convenient and prominently visible
-feature that (1) displays an appropriate copyright notice, and (2)
-tells the user that there is no warranty for the work (except to the
-extent that warranties are provided), that licensees may convey the
-work under this License, and how to view a copy of this License.  If
-the interface presents a list of user commands or options, such as a
-menu, a prominent item in the list meets this criterion.
-
-  1. Source Code.
-
-  The "source code" for a work means the preferred form of the work
-for making modifications to it.  "Object code" means any non-source
-form of a work.
-
-  A "Standard Interface" means an interface that either is an official
-standard defined by a recognized standards body, or, in the case of
-interfaces specified for a particular programming language, one that
-is widely used among developers working in that language.
-
-  The "System Libraries" of an executable work include anything, other
-than the work as a whole, that (a) is included in the normal form of
-packaging a Major Component, but which is not part of that Major
-Component, and (b) serves only to enable use of the work with that
-Major Component, or to implement a Standard Interface for which an
-implementation is available to the public in source code form.  A
-"Major Component", in this context, means a major essential component
-(kernel, window system, and so on) of the specific operating system
-(if any) on which the executable work runs, or a compiler used to
-produce the work, or an object code interpreter used to run it.
-
-  The "Corresponding Source" for a work in object code form means all
-the source code needed to generate, install, and (for an executable
-work) run the object code and to modify the work, including scripts to
-control those activities.  However, it does not include the work's
-System Libraries, or general-purpose tools or generally available free
-programs which are used unmodified in performing those activities but
-which are not part of the work.  For example, Corresponding Source
-includes interface definition files associated with source files for
-the work, and the source code for shared libraries and dynamically
-linked subprograms that the work is specifically designed to require,
-such as by intimate data communication or control flow between those
-subprograms and other parts of the work.
-
-  The Corresponding Source need not include anything that users
-can regenerate automatically from other parts of the Corresponding
-Source.
-
-  The Corresponding Source for a work in source code form is that
-same work.
-
-  2. Basic Permissions.
-
-  All rights granted under this License are granted for the term of
-copyright on the Program, and are irrevocable provided the stated
-conditions are met.  This License explicitly affirms your unlimited
-permission to run the unmodified Program.  The output from running a
-covered work is covered by this License only if the output, given its
-content, constitutes a covered work.  This License acknowledges your
-rights of fair use or other equivalent, as provided by copyright law.
-
-  You may make, run and propagate covered works that you do not
-convey, without conditions so long as your license otherwise remains
-in force.  You may convey covered works to others for the sole purpose
-of having them make modifications exclusively for you, or provide you
-with facilities for running those works, provided that you comply with
-the terms of this License in conveying all material for which you do
-not control copyright.  Those thus making or running the covered works
-for you must do so exclusively on your behalf, under your direction
-and control, on terms that prohibit them from making any copies of
-your copyrighted material outside their relationship with you.
-
-  Conveying under any other circumstances is permitted solely under
-the conditions stated below.  Sublicensing is not allowed; section 10
-makes it unnecessary.
-
-  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
-
-  No covered work shall be deemed part of an effective technological
-measure under any applicable law fulfilling obligations under article
-11 of the WIPO copyright treaty adopted on 20 December 1996, or
-similar laws prohibiting or restricting circumvention of such
-measures.
-
-  When you convey a covered work, you waive any legal power to forbid
-circumvention of technological measures to the extent such circumvention
-is effected by exercising rights under this License with respect to
-the covered work, and you disclaim any intention to limit operation or
-modification of the work as a means of enforcing, against the work's
-users, your or third parties' legal rights to forbid circumvention of
-technological measures.
-
-  4. Conveying Verbatim Copies.
-
-  You may convey verbatim copies of the Program's source code as you
-receive it, in any medium, provided that you conspicuously and
-appropriately publish on each copy an appropriate copyright notice;
-keep intact all notices stating that this License and any
-non-permissive terms added in accord with section 7 apply to the code;
-keep intact all notices of the absence of any warranty; and give all
-recipients a copy of this License along with the Program.
-
-  You may charge any price or no price for each copy that you convey,
-and you may offer support or warranty protection for a fee.
-
-  5. Conveying Modified Source Versions.
-
-  You may convey a work based on the Program, or the modifications to
-produce it from the Program, in the form of source code under the
-terms of section 4, provided that you also meet all of these conditions:
-
-    a) The work must carry prominent notices stating that you modified
-    it, and giving a relevant date.
-
-    b) The work must carry prominent notices stating that it is
-    released under this License and any conditions added under section
-    7.  This requirement modifies the requirement in section 4 to
-    "keep intact all notices".
-
-    c) You must license the entire work, as a whole, under this
-    License to anyone who comes into possession of a copy.  This
-    License will therefore apply, along with any applicable section 7
-    additional terms, to the whole of the work, and all its parts,
-    regardless of how they are packaged.  This License gives no
-    permission to license the work in any other way, but it does not
-    invalidate such permission if you have separately received it.
-
-    d) If the work has interactive user interfaces, each must display
-    Appropriate Legal Notices; however, if the Program has interactive
-    interfaces that do not display Appropriate Legal Notices, your
-    work need not make them do so.
-
-  A compilation of a covered work with other separate and independent
-works, which are not by their nature extensions of the covered work,
-and which are not combined with it such as to form a larger program,
-in or on a volume of a storage or distribution medium, is called an
-"aggregate" if the compilation and its resulting copyright are not
-used to limit the access or legal rights of the compilation's users
-beyond what the individual works permit.  Inclusion of a covered work
-in an aggregate does not cause this License to apply to the other
-parts of the aggregate.
-
-  6. Conveying Non-Source Forms.
-
-  You may convey a covered work in object code form under the terms
-of sections 4 and 5, provided that you also convey the
-machine-readable Corresponding Source under the terms of this License,
-in one of these ways:
-
-    a) Convey the object code in, or embodied in, a physical product
-    (including a physical distribution medium), accompanied by the
-    Corresponding Source fixed on a durable physical medium
-    customarily used for software interchange.
-
-    b) Convey the object code in, or embodied in, a physical product
-    (including a physical distribution medium), accompanied by a
-    written offer, valid for at least three years and valid for as
-    long as you offer spare parts or customer support for that product
-    model, to give anyone who possesses the object code either (1) a
-    copy of the Corresponding Source for all the software in the
-    product that is covered by this License, on a durable physical
-    medium customarily used for software interchange, for a price no
-    more than your reasonable cost of physically performing this
-    conveying of source, or (2) access to copy the
-    Corresponding Source from a network server at no charge.
-
-    c) Convey individual copies of the object code with a copy of the
-    written offer to provide the Corresponding Source.  This
-    alternative is allowed only occasionally and noncommercially, and
-    only if you received the object code with such an offer, in accord
-    with subsection 6b.
-
-    d) Convey the object code by offering access from a designated
-    place (gratis or for a charge), and offer equivalent access to the
-    Corresponding Source in the same way through the same place at no
-    further charge.  You need not require recipients to copy the
-    Corresponding Source along with the object code.  If the place to
-    copy the object code is a network server, the Corresponding Source
-    may be on a different server (operated by you or a third party)
-    that supports equivalent copying facilities, provided you maintain
-    clear directions next to the object code saying where to find the
-    Corresponding Source.  Regardless of what server hosts the
-    Corresponding Source, you remain obligated to ensure that it is
-    available for as long as needed to satisfy these requirements.
-
-    e) Convey the object code using peer-to-peer transmission, provided
-    you inform other peers where the object code and Corresponding
-    Source of the work are being offered to the general public at no
-    charge under subsection 6d.
-
-  A separable portion of the object code, whose source code is excluded
-from the Corresponding Source as a System Library, need not be
-included in conveying the object code work.
-
-  A "User Product" is either (1) a "consumer product", which means any
-tangible personal property which is normally used for personal, family,
-or household purposes, or (2) anything designed or sold for incorporation
-into a dwelling.  In determining whether a product is a consumer product,
-doubtful cases shall be resolved in favor of coverage.  For a particular
-product received by a particular user, "normally used" refers to a
-typical or common use of that class of product, regardless of the status
-of the particular user or of the way in which the particular user
-actually uses, or expects or is expected to use, the product.  A product
-is a consumer product regardless of whether the product has substantial
-commercial, industrial or non-consumer uses, unless such uses represent
-the only significant mode of use of the product.
-
-  "Installation Information" for a User Product means any methods,
-procedures, authorization keys, or other information required to install
-and execute modified versions of a covered work in that User Product from
-a modified version of its Corresponding Source.  The information must
-suffice to ensure that the continued functioning of the modified object
-code is in no case prevented or interfered with solely because
-modification has been made.
-
-  If you convey an object code work under this section in, or with, or
-specifically for use in, a User Product, and the conveying occurs as
-part of a transaction in which the right of possession and use of the
-User Product is transferred to the recipient in perpetuity or for a
-fixed term (regardless of how the transaction is characterized), the
-Corresponding Source conveyed under this section must be accompanied
-by the Installation Information.  But this requirement does not apply
-if neither you nor any third party retains the ability to install
-modified object code on the User Product (for example, the work has
-been installed in ROM).
-
-  The requirement to provide Installation Information does not include a
-requirement to continue to provide support service, warranty, or updates
-for a work that has been modified or installed by the recipient, or for
-the User Product in which it has been modified or installed.  Access to a
-network may be denied when the modification itself materially and
-adversely affects the operation of the network or violates the rules and
-protocols for communication across the network.
-
-  Corresponding Source conveyed, and Installation Information provided,
-in accord with this section must be in a format that is publicly
-documented (and with an implementation available to the public in
-source code form), and must require no special password or key for
-unpacking, reading or copying.
-
-  7. Additional Terms.
-
-  "Additional permissions" are terms that supplement the terms of this
-License by making exceptions from one or more of its conditions.
-Additional permissions that are applicable to the entire Program shall
-be treated as though they were included in this License, to the extent
-that they are valid under applicable law.  If additional permissions
-apply only to part of the Program, that part may be used separately
-under those permissions, but the entire Program remains governed by
-this License without regard to the additional permissions.
-
-  When you convey a copy of a covered work, you may at your option
-remove any additional permissions from that copy, or from any part of
-it.  (Additional permissions may be written to require their own
-removal in certain cases when you modify the work.)  You may place
-additional permissions on material, added by you to a covered work,
-for which you have or can give appropriate copyright permission.
-
-  Notwithstanding any other provision of this License, for material you
-add to a covered work, you may (if authorized by the copyright holders of
-that material) supplement the terms of this License with terms:
-
-    a) Disclaiming warranty or limiting liability differently from the
-    terms of sections 15 and 16 of this License; or
-
-    b) Requiring preservation of specified reasonable legal notices or
-    author attributions in that material or in the Appropriate Legal
-    Notices displayed by works containing it; or
-
-    c) Prohibiting misrepresentation of the origin of that material, or
-    requiring that modified versions of such material be marked in
-    reasonable ways as different from the original version; or
-
-    d) Limiting the use for publicity purposes of names of licensors or
-    authors of the material; or
-
-    e) Declining to grant rights under trademark law for use of some
-    trade names, trademarks, or service marks; or
-
-    f) Requiring indemnification of licensors and authors of that
-    material by anyone who conveys the material (or modified versions of
-    it) with contractual assumptions of liability to the recipient, for
-    any liability that these contractual assumptions directly impose on
-    those licensors and authors.
-
-  All other non-permissive additional terms are considered "further
-restrictions" within the meaning of section 10.  If the Program as you
-received it, or any part of it, contains a notice stating that it is
-governed by this License along with a term that is a further
-restriction, you may remove that term.  If a license document contains
-a further restriction but permits relicensing or conveying under this
-License, you may add to a covered work material governed by the terms
-of that license document, provided that the further restriction does
-not survive such relicensing or conveying.
-
-  If you add terms to a covered work in accord with this section, you
-must place, in the relevant source files, a statement of the
-additional terms that apply to those files, or a notice indicating
-where to find the applicable terms.
-
-  Additional terms, permissive or non-permissive, may be stated in the
-form of a separately written license, or stated as exceptions;
-the above requirements apply either way.
-
-  8. Termination.
-
-  You may not propagate or modify a covered work except as expressly
-provided under this License.  Any attempt otherwise to propagate or
-modify it is void, and will automatically terminate your rights under
-this License (including any patent licenses granted under the third
-paragraph of section 11).
-
-  However, if you cease all violation of this License, then your
-license from a particular copyright holder is reinstated (a)
-provisionally, unless and until the copyright holder explicitly and
-finally terminates your license, and (b) permanently, if the copyright
-holder fails to notify you of the violation by some reasonable means
-prior to 60 days after the cessation.
-
-  Moreover, your license from a particular copyright holder is
-reinstated permanently if the copyright holder notifies you of the
-violation by some reasonable means, this is the first time you have
-received notice of violation of this License (for any work) from that
-copyright holder, and you cure the violation prior to 30 days after
-your receipt of the notice.
-
-  Termination of your rights under this section does not terminate the
-licenses of parties who have received copies or rights from you under
-this License.  If your rights have been terminated and not permanently
-reinstated, you do not qualify to receive new licenses for the same
-material under section 10.
-
-  9. Acceptance Not Required for Having Copies.
-
-  You are not required to accept this License in order to receive or
-run a copy of the Program.  Ancillary propagation of a covered work
-occurring solely as a consequence of using peer-to-peer transmission
-to receive a copy likewise does not require acceptance.  However,
-nothing other than this License grants you permission to propagate or
-modify any covered work.  These actions infringe copyright if you do
-not accept this License.  Therefore, by modifying or propagating a
-covered work, you indicate your acceptance of this License to do so.
-
-  10. Automatic Licensing of Downstream Recipients.
-
-  Each time you convey a covered work, the recipient automatically
-receives a license from the original licensors, to run, modify and
-propagate that work, subject to this License.  You are not responsible
-for enforcing compliance by third parties with this License.
-
-  An "entity transaction" is a transaction transferring control of an
-organization, or substantially all assets of one, or subdividing an
-organization, or merging organizations.  If propagation of a covered
-work results from an entity transaction, each party to that
-transaction who receives a copy of the work also receives whatever
-licenses to the work the party's predecessor in interest had or could
-give under the previous paragraph, plus a right to possession of the
-Corresponding Source of the work from the predecessor in interest, if
-the predecessor has it or can get it with reasonable efforts.
-
-  You may not impose any further restrictions on the exercise of the
-rights granted or affirmed under this License.  For example, you may
-not impose a license fee, royalty, or other charge for exercise of
-rights granted under this License, and you may not initiate litigation
-(including a cross-claim or counterclaim in a lawsuit) alleging that
-any patent claim is infringed by making, using, selling, offering for
-sale, or importing the Program or any portion of it.
-
-  11. Patents.
-
-  A "contributor" is a copyright holder who authorizes use under this
-License of the Program or a work on which the Program is based.  The
-work thus licensed is called the contributor's "contributor version".
-
-  A contributor's "essential patent claims" are all patent claims
-owned or controlled by the contributor, whether already acquired or
-hereafter acquired, that would be infringed by some manner, permitted
-by this License, of making, using, or selling its contributor version,
-but do not include claims that would be infringed only as a
-consequence of further modification of the contributor version.  For
-purposes of this definition, "control" includes the right to grant
-patent sublicenses in a manner consistent with the requirements of
-this License.
-
-  Each contributor grants you a non-exclusive, worldwide, royalty-free
-patent license under the contributor's essential patent claims, to
-make, use, sell, offer for sale, import and otherwise run, modify and
-propagate the contents of its contributor version.
-
-  In the following three paragraphs, a "patent license" is any express
-agreement or commitment, however denominated, not to enforce a patent
-(such as an express permission to practice a patent or covenant not to
-sue for patent infringement).  To "grant" such a patent license to a
-party means to make such an agreement or commitment not to enforce a
-patent against the party.
-
-  If you convey a covered work, knowingly relying on a patent license,
-and the Corresponding Source of the work is not available for anyone
-to copy, free of charge and under the terms of this License, through a
-publicly available network server or other readily accessible means,
-then you must either (1) cause the Corresponding Source to be so
-available, or (2) arrange to deprive yourself of the benefit of the
-patent license for this particular work, or (3) arrange, in a manner
-consistent with the requirements of this License, to extend the patent
-license to downstream recipients.  "Knowingly relying" means you have
-actual knowledge that, but for the patent license, your conveying the
-covered work in a country, or your recipient's use of the covered work
-in a country, would infringe one or more identifiable patents in that
-country that you have reason to believe are valid.
-
-  If, pursuant to or in connection with a single transaction or
-arrangement, you convey, or propagate by procuring conveyance of, a
-covered work, and grant a patent license to some of the parties
-receiving the covered work authorizing them to use, propagate, modify
-or convey a specific copy of the covered work, then the patent license
-you grant is automatically extended to all recipients of the covered
-work and works based on it.
-
-  A patent license is "discriminatory" if it does not include within
-the scope of its coverage, prohibits the exercise of, or is
-conditioned on the non-exercise of one or more of the rights that are
-specifically granted under this License.  You may not convey a covered
-work if you are a party to an arrangement with a third party that is
-in the business of distributing software, under which you make payment
-to the third party based on the extent of your activity of conveying
-the work, and under which the third party grants, to any of the
-parties who would receive the covered work from you, a discriminatory
-patent license (a) in connection with copies of the covered work
-conveyed by you (or copies made from those copies), or (b) primarily
-for and in connection with specific products or compilations that
-contain the covered work, unless you entered into that arrangement,
-or that patent license was granted, prior to 28 March 2007.
-
-  Nothing in this License shall be construed as excluding or limiting
-any implied license or other defenses to infringement that may
-otherwise be available to you under applicable patent law.
-
-  12. No Surrender of Others' Freedom.
-
-  If conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License.  If you cannot convey a
-covered work so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you may
-not convey it at all.  For example, if you agree to terms that obligate you
-to collect a royalty for further conveying from those to whom you convey
-the Program, the only way you could satisfy both those terms and this
-License would be to refrain entirely from conveying the Program.
-
-  13. Use with the GNU Affero General Public License.
-
-  Notwithstanding any other provision of this License, you have
-permission to link or combine any covered work with a work licensed
-under version 3 of the GNU Affero General Public License into a single
-combined work, and to convey the resulting work.  The terms of this
-License will continue to apply to the part which is the covered work,
-but the special requirements of the GNU Affero General Public License,
-section 13, concerning interaction through a network will apply to the
-combination as such.
-
-  14. Revised Versions of this License.
-
-  The Free Software Foundation may publish revised and/or new versions of
-the GNU General Public License from time to time.  Such new versions will
-be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-
-  Each version is given a distinguishing version number.  If the
-Program specifies that a certain numbered version of the GNU General
-Public License "or any later version" applies to it, you have the
-option of following the terms and conditions either of that numbered
-version or of any later version published by the Free Software
-Foundation.  If the Program does not specify a version number of the
-GNU General Public License, you may choose any version ever published
-by the Free Software Foundation.
-
-  If the Program specifies that a proxy can decide which future
-versions of the GNU General Public License can be used, that proxy's
-public statement of acceptance of a version permanently authorizes you
-to choose that version for the Program.
-
-  Later license versions may give you additional or different
-permissions.  However, no additional obligations are imposed on any
-author or copyright holder as a result of your choosing to follow a
-later version.
-
-  15. Disclaimer of Warranty.
-
-  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
-APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
-HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
-OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
-THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
-PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
-IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
-ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
-
-  16. Limitation of Liability.
-
-  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
-THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
-GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
-USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
-DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
-PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
-EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
-SUCH DAMAGES.
-
-  17. Interpretation of Sections 15 and 16.
-
-  If the disclaimer of warranty and limitation of liability provided
-above cannot be given local legal effect according to their terms,
-reviewing courts shall apply local law that most closely approximates
-an absolute waiver of all civil liability in connection with the
-Program, unless a warranty or assumption of liability accompanies a
-copy of the Program in return for a fee.
-
-                     END OF TERMS AND CONDITIONS
-
-            How to Apply These Terms to Your New Programs
-
-  If you develop a new program, and you want it to be of the greatest
-possible use to the public, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these terms.
-
-  To do so, attach the following notices to the program.  It is safest
-to attach them to the start of each source file to most effectively
-state the exclusion of warranty; and each file should have at least
-the "copyright" line and a pointer to where the full notice is found.
-
-    <one line to give the program's name and a brief idea of what it does.>
-    Copyright (C) <year>  <name of author>
-
-    This program is free software: you can redistribute it and/or modify
-    it under the terms of the GNU General Public License as published by
-    the Free Software Foundation, either version 3 of the License, or
-    (at your option) any later version.
-
-    This program is distributed in the hope that it will be useful,
-    but WITHOUT ANY WARRANTY; without even the implied warranty of
-    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
-    GNU General Public License for more details.
-
-    You should have received a copy of the GNU General Public License
-    along with this program.  If not, see <https://www.gnu.org/licenses/>.
-
-Also add information on how to contact you by electronic and paper mail.
-
-  If the program does terminal interaction, make it output a short
-notice like this when it starts in an interactive mode:
-
-    <program>  Copyright (C) <year>  <name of author>
-    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
-    This is free software, and you are welcome to redistribute it
-    under certain conditions; type `show c' for details.
-
-The hypothetical commands `show w' and `show c' should show the appropriate
-parts of the General Public License.  Of course, your program's commands
-might be different; for a GUI interface, you would use an "about box".
-
-  You should also get your employer (if you work as a programmer) or school,
-if any, to sign a "copyright disclaimer" for the program, if necessary.
-For more information on this, and how to apply and follow the GNU GPL, see
-<https://www.gnu.org/licenses/>.
-
-  The GNU General Public License does not permit incorporating your program
-into proprietary programs.  If your program is a subroutine library, you
-may consider it more useful to permit linking proprietary applications with
-the library.  If this is what you want to do, use the GNU Lesser General
-Public License instead of this License.  But first, please read
-<https://www.gnu.org/licenses/why-not-lgpl.html>.

 # Terra
 
-Terra is an incredibly powerful free & open-source data-driven, platform-agnostic world generator. It allows you to create a world exactly
-to your specifications, with no knowledge of Java required.
+Terra is a modern world generation modding platform, primarily for Minecraft.
+Terra allows complete customization of world generation with an advanced API,
+tightly integrated with a powerful configuration system.
+
+Terra consists of several parts:
+
+* A voxel world generation API with emphasis on configuration and extensibility
+* Several platform implementations, the layer between the API and the platform
+  it's running on.
+* An addon loader, which allows addons to interface with the Terra API in a
+  platform-agnostic setting
+* Several "core addons," which implement the "default" configurations of Terra.
+  These addons can be thought of as the config "standard library"
+
+Terra currently officially supports the Fabric mod loader and the Bukkit API
+(Paper and friends). We welcome Pull Requests implementing additional platforms!

+# biome-provider-pipeline-2
+
+The second version of the Biome Pipeline, a procedural biome provider that uses a series
+of "stages" to apply "mutations" to a 2D grid of biomes.
+
+Version 2 is a re-implementation of the original addon with the primary goal of providing
+consistent scaling for noise relative to the world
+(See https://github.com/PolyhedralDev/Terra/issues/264 for more details), and has been
+included as a separate addon to maintain parity with packs utilizing the first version.
+
+This addon registers the `PIPELINE` biome provider type, and all associated
+configurations.
