+## Make use of LuaJIT-2.0.4
+1. Check LuaJITs doc for compiling it on [Windows](https://luajit.org/install.html#windows).
+2. After compiling LuaJIT, copy the following files into destination directory: ([Double check here on 3.](https://gist.github.com/Egor-Skriptunoff/cb952f7eaf39b7b1bf739b818ece87cd))
+   - `luajit.exe` and `lua51.dll` (`lua51.lib`?) into `NoitaMP\LuaJIT-2.0.4\bin`
+   - Install jit.* modules by copying `NoitaMP\.building\LuaJIT-2.0.4\src\jit` into `NoitaMP\LuaJIT-2.0.4\jit`
+   - Add includes by copying `lauxlib.h`, `lua.h`, `lua.hpp`, `luaconf.h`, `lualib.h` from `NoitaMP\.building\LuaJIT-2.0.4\src` into `NoitaMP\LuaJIT-2.0.4\include`
+3. Change `config-5.1.lua` like so, but use your local absolute path to `NoitaMP\LuaJIT-2.0.4\`:
+   ```lua
+   lua_interpreter = "luajit.exe"
+   variables = {
+    LUA_BINDIR = "yourAbsolutePathTo\\NoitaMP\\LuaJIT-2.0.4\\bin", -- LUA_BINDIR = "C:\\msys64\\mingw32\\bin",
+    LUA_DIR = "yourAbsolutePathTo\\NoitaMP\\LuaJIT-2.0.4", -- LUA_DIR = "C:\\msys64\\mingw32",
+    LUA_INCDIR = "yourAbsolutePathTo\\NoitaMP\\LuaJIT-2.0.4\\include" -- LUA_INCDIR = "C:\\msys64\\mingw32/include/lua5.1"
+   }
+   ```
+4. Run `luarocks` in `\NoitaMP\mods\noita-mp` directory again. Done!
