 ### Linux
-Linux is well.. complicated
+Linux is a bit more complicated, as obviously there's no linux release of GD (yet). Of course, you can run the Windows version of GD through software like [wine](https://www.winehq.org/) quite well, which is probably what you're already doing.

+Because of that, this guide will set you up to [cross-compile](https://en.wikipedia.org/wiki/Cross_compiler) windows Geode mods from linux.

 # Profile Setup
