 Building from Source
 ====================
-If you want to build from source, follow the instructions above for your platform, but don't do `pip install pyboy`. If PyBoy is already installed, make sure to uninstall it with `pip uninstall pyboy`. Run the uninstall more than once, to make sure you don't have multiple versions installed.

+Next clone and build RGBDS (Rednex Game Boy Development System).
