 # Server Manual
 
-Server Name is limited to 250 characters
-Server Description is limited to 1000 characters
-Map is limited to 100 characters
-Tags is limited to 100 characters
+# Environment
+
+The server is affected by the state of various external parameters:
+- The "Resources" folder
+- The ENV (process environment)
+- The commandline arguments
+- The ServerConfig.toml file
+- The working directory
+
+## Resources Folder
+
+The resources folder is created upon startup of the server, together with the "Client" and "Server" subdirectories.
+The "Server" subdirectory accepts folders within it, each containing at least one `.lua` file. Each of these folders in the "Server" subdirectory is called a "Plugin". `.lua` files contained in the top-level directory of a plugin are hot-reloaded on change.
+The "Client" subdirectory accepts *only* `.zip` files, which are loaded when the server starts, and assumed to not change during runtime.
+
+## ENV
+
+As of Server release v3.2.0, the BeamMP Server accepts environment variables, which **override** settings in the ServerConfig.toml. All ServerConfig variables which exist in the "General" category/section are PascalCase, the environment variables are ALL_CAPS and prefixed with `BEAMMP_`. For example, the `MaxPlayers` setting converted to ALL_CAPS is `MAX_PLAYERS` (note the `_` where a new word starts), and prefixed it becomes `BEAMMP_MAX_PLAYERS`. This is the format followed for all "General" settings. More examples follow:
+
+- `AuthKey` -> `BEAMMP_AUTH_KEY`
+- `Port` -> `BEAMMP_PORT`
+- `Description` -> `BEAMMP_DESCRIPTION`
+- ... etc.
+
+Any environment variables corresponding to config parameters which are strings or numbers must be strings, for example `BEAMMP_NAME="Cool Server"`, `BEAMMP_NAME=Server1`, `BEAMMP_PORT=12345`.
+Environment variables corresponding to config parameters which are booleans (true/false, on/off) must be either `true` or `1` (both meaning ON), or any other value (meaning OFF).
+
+## Commandline arguments
+
+Run the BeamMP Server with the `--help` argument to learn more. For example: `./BeamMP-Server --help`.
+
+## ServerConfig.toml
+
+This file is generated on first startup. Comments inside the file are the most up-to-date way to understand what each setting does.
+
+## Working directory
+
+The working directory of the server, not the location of the server executable, is the deciding factor on where the ServerConfig.toml, server log files, and Resources folder, are generated.
+
+# Limitations
+
+The following limitations are enforced in the BeamMP Backend, which affects the Servers:
+
+- Name is limited to 250 characters
+- Description is limited to 1000 characters
+- Map is limited to 100 characters
+- Tags are limited to 100 characters
