+# Integration Modules
+This adds support for 3rd party libraries to the engine. These can be included in projects
+to expose modules which can then be used in your applications.
+
+## Integrations Provided
+The following integration modules are povided in this folder. For more information please see the readme for that module.
+
+| Integration | Module Name           | Description                                        |
+|-------------|-----------------------|----------------------------------------------------|
+| Bullet      | `fggl::phys::Bullet3` | Provides Bullet3 integration into the game engine. |
+| Lua         | `fggl::script::Lua`   | Provides LUA scripting support for the engine      |
+
+Modules that cannot be included for legal reasons will be packaged independently of this repository.
