 A very simple Python framework that allows you to write official Windows screen savers using
 Python and the [Arcade](https://github.com/pythonarcade/arcade) 2D video game library.
 
-Most Arcade applications that use the class-centric Arcade API (ex: derive a window from `arcade.Window`)
-can be made into a Windows screen saver. Usually, it is as simple as adding the framework import to your
