+This program started life as a friendly fork of Quinn Dunki's `HiSprite
 <https://github.com/blondie7575/HiSprite>`_ that she presented at KansasFest
 2017.
 
+Her conclusion was that it was not that practical for the Apple II because of
+the limited memory and the number of sprite shifts needed. I wanted to port
+this to the Atari because it would require fewer shifted shapes in most of the
+graphics modes (e.g. only 4 shifted shapes for the commonly used ANTIC modes 13
+and 14) She told me that she was unlikely to continue work on sprite compiling
+but encouraged me to continue development.
