+### Windows Subsystem for Linux
+
+While pixel does run on Windows, you will likely have significantly better performance running in WSL2, which now has support for GUI applications built-in with WSLg.
+
+Installation instructions [here](https://github.com/microsoft/wslg?tab=readme-ov-file#installing-wslg). If you already have an old version of WSL installed, 
+make sure to follow the upgrade instructions to get WSL2 as well as update your distribution of choice to version 2. Additionally, if you have an old `DISPLAY` environment variable set in your ~/.bashrc (or equivalent) for WSL1, you should remove it. This is now configured automatically.
+
+Once WSL is setup, follow the usual Go and OpenGL installation instructions for your chosen distribution of linux.
+
+Finally, add `export LIBGL_ALWAYS_INDIRECT=0` to your ~/.bashrc (or equivalent) if you see an error like `Error: creating window failed: VersionUnavailable: GLX: Failed to create context: GLXBadFBConfig` when attempting to launch an OpenGL application from WSL.
