 ## Empire at War Lua Scripting Engine
 
-The source code for the Lua scripting engine in Empire at War was leaked at: https://github.com/PetroglyphGames/GlyphX-Reference. Use this as a guide for what Lua functions and variables are already available, and how the engine hooks Lua scripting into the rest of the game. No other engine source code is available.

+## Adding a New Lua Function
+
+1. Create `functions/<module>.cpp` — implement `L_*` function(s) and `Register_<Module>(lua_State* L)`
+2. Add `void Register_<Module>(lua_State* L);` to `functions/functions.h`
+3. Add `Register_<Module>(L);` to `functions/functions.cpp`
+4. Add new RVAs (if needed) to `rvas.h` in the relevant section, for each supported executable
+5. Add `functions\<module>.cpp` to `FoCAPI.vcxproj` and `FoCAPI.vcxproj.filters`
