 ## Project Overview
 
-This project is a hook API for Star Wars: Empire at War: Forces of Corruption to expose custom Lua functions available for scripting.
+This project is a DLL hook for Star Wars: Empire at War: Forces of Corruption to add custom Lua functions available for scripting.
 
 ## Client and Debug Kits
 
 - StarWarsG.exe -- the binary shipped with the game for all clients. PDB unavailable.
 - StarWarsI.exe -- the debug kit binary which comes with debug functionality but is too slow to run normally. PDB available.
+- Both binares are 64-bit Windows portable executables.
 
 ## DLL Hook
 
 - Uses MinHook to create the DLL hook into the game via powerprof.dll
-- Using IDA Free to find addresses of function calls.
+- Using Ghidra to find addresses of function calls from StarWarsI and map them using Version Control to addresses in StarWarsG.
 
 ## 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.
+The source code for parts of the Lua scripting engine in Empire at War was leaked at and can be accessed [here](../GlyphX-Reference-master/Project1/Code/). 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.
+
+## 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`

-# SWEaW Hooks
+# FoCAPI
 
 A powrprof.dll hook which adds custom Lua functions to Forces of Corruption.
 
 ## Usage
 
-Drop powrprof.dll and MinHooks.x64.dll into the `/corruption/` folder of your Empire at War installation.
+Drop powrprof.dll and MinHooks.x64.dll into the `/corruption` folder of your Empire at War installation.
-Currently only works with the debug kit `StarWarsI.exe`; `StarWarsG.exe` support is coming soon.
+Works with both the debug kit `StarWarsI.exe` and client version `StarWarsG.exe` of the Steam version.
+Not supported on disc / GoG versions (sorry).
 
-## Functions
+## Global Functions
 
-- Global `WriteToFile(str a, str b)` - Appends a line of text `b` to the file name `a` in the game directory.
+- Global `WriteToFile(file, text)` - Appends a line of text specified file in the game directory.
+  - Parameter `file` string - The file name to append.
+  - Parameter `text` string - The text line to append.
+- Global `Get_All_Players()` - Returns a 1-based Lua table of all active players, iterable with `ipairs()`. Each entry is the same PlayerWrapper type returned by `Find_Player()`.
+- Global `Add_Tutorial_Text(key, text, duration, r, g, b, a)` - Adds a line to the tutorial text pane.
+  - Parameter `key`: string - The key used to identify this line, later can be used to update or remove the text.
+  - Parameter `text`: string - The text to display.
+  - Parameter `duration` number? - The duration to display the text. Default: -1 (infinite)
+  - Parameter `r` number? - The red color component. Default: 1
+  - Parameter `g` number? - The green color component. Default: 1
+  - Parameter `b` number? - The blue color component. Default: 1
+  - Parameter `a` number? - The alpha component. Default: 1
+- Global `Remove_Tutorial_Text(key)` - Removes the line associated with the key.
+  - Parameter `key` string - The key used to identify the line when it was added.
+  
+## GameObjectTypeWrapper
+
+- `Get_Display_Name()` - Returns the localized text string display name of the object type.
