## What it is
The public repository of Lua, text, and config extensions for Garry's Mod, a physics sandbox game built on a modified version of Valve's Source Engine. The binary game sources are not public, but this repo contains all the scriptable game logic and welcomes community pull requests.

## Use cases
- contribute Lua code or fixes to Garry's Mod
- browse the game's Lua source to learn GMod Lua scripting
- develop addons that hook into Garry's Mod's Lua API
- report or track game bugs and feature requests
- contribute translations for the game
- preview upcoming changes on the dev branch

## When to choose
- you want to read or contribute to the actual Lua codebase of Garry's Mod
- you are a GMod addon developer needing the authoritative game-side Lua sources
- you want to follow or test upcoming game updates

## When to avoid
- you want the full game binary source code - only Lua/config extensions are public
- you want to build a standalone game from scratch on Source
- you need a general-purpose game engine rather than a specific game's scripts
