+# Interface Files
+
+This directory holds the documentation for the Lua C API that
+is hidden in the C source files of Lite. The idea of these files
+is to serve you as a quick reference about the functionality
+that is not written in Lua it self. Please note that they
+don't have any real code, just metadata or annotations.
+
+Also, these interfaces are using
+[EmmyLua annotation syntax](https://emmylua.github.io/annotation.html)
+which is supported by LSP servers like the
+[Sumneko Lua LSP](https://github.com/sumneko/lua-language-server).
+This means that you can get nice code autocompletion and descriptions
+of Lite core libraries and symbols when developing plugins or adding
+any options to your **User Module File** (init.lua).
+
+## The Base Core
+
+Most of the code that is written in Lua for Lite is powered by the exposed
+C API in the four namespaces that follow:
+
+* [system](api/system.lua)
+* [renderer](api/renderer.lua)
+* [regex](api/regex.lua)
+* [process](api/process.lua)
+
+Finally, all global variables are documented in the file named
+[globals.lua](api/globals.lua).
