+## 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)
+    - email: [solonovamax@12oclockpoint.com](mailto:solonovamax@12oclockpoint.com)

+    - 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.

+## 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
+'dream/dreamself' (pronouns related to real people, eg. the minecraft youtuber 'dreamwastaken'). 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 main project.
+  *General* compatibility (e.g. "Ability to pull Vanilla/Modded features from parent biomes") will be considered in the main 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 main 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
+
+This section guides you through submitting a pull request for Terra.
+
+While the prerequisites above must be satisfied prior to having your pull request reviewed, the reviewer(s) may ask you to complete
+additional design work, tests, or other changes before your pull request can be ultimately accepted.

+## 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.
+
+### Documentation Styleguide
+
+TODO
+
+## Coding Practices
+
+### Compatibility
+
+#### General Compatibility
+
+General compatibility (example: injection of Vanilla structures/features/carvers into packs) is acceptable in the main 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 main 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.
