+## Building the launcher or mods
+This project will only ever support GCC. This program will not even build using MSVC, not only because the inline assembly syntax is different, but because support for inline assembly was removed for x86-64.

+All mods MUST include cwmods.h from [cwsdk](https://github.com/ChrisMiuchiz/CWSDK) to function.
