We are open to contributions, either adding new functions, improving documentation or fixing some bugs.
If you add new functions, please also document them. We do our documentation in ReadTheDocs. Everything is in the docs directory, it uses reStructuredText, this cheatsheet should help if you don't know it.
Basically all you need is sphinx (pip install sphinx sphinx-rtd-theme), and then you can run make html from inside the docs directory.
Pro Tip: This Dockerfile makes it easy to test documentation locally. You won't need to install anything (if you already have docker) and it enables live reload of the documentation when you change anything.
First, download the SteamWorks SDK, and unzip it on this directory.
Install package libluajit-5.1-dev. Run make linux64.
Install package libluajit-5.1-dev:i386. Run make linux32. This assumes you're using a 64 bit OS.
Install luajit (brew install luajit). Run make osx.
Download VSCode and LuaJIT source. Build it using "x64_86 Cross Tools Command Prompt for VS 2017" (or similar, depending if you want x86 or x64 and what platform you have) (instructions).
Copy source files from LuaJIT-2.0.5\src to a luajit directory inside this directory. Copy LuaJIT-2.0.5\src\lua51.lib to this directory. Then run nmake windows32 or nmake windows64, this will create the luasteam.dll file.
If you're building for both Windows 32 and 64, remember to rebuild LuaJIT and copy lua51.lib again for the correct platform.
