 ## Requirements
 
-If you're using Windows and having trouble building Pixel, please check [this
-guide](https://github.com/gopxl/pixel/wiki/Building-Pixel-on-Windows) on the
-[wiki](https://github.com/gopxl/pixel/wiki). Alternatively you can try running on WSL, as described [below](#windows-subsystem-for-linux).
+If you're using Windows and having trouble building Pixel, please check [this guide](./docs/Compilation/Building-Pixel-on-Windows.md) on the [wiki](./docs/README.md).
 
 OpenGL development libraries are needed for compilation. The dependencies
 are same as for [GLFW](https://github.com/go-gl/glfw).
