 # Purpose
 
-This repository is intended to hold some of the most useful, higher-level widgets
-that are native to tkinter.  This library is currently compatible with Python 3.5+ (uses
-type hints), but could easily be back-ported to earlier versions if desired.

+This library used type hints and requires Python 3.5+; it could, however, be back-ported to earlier Python versions without difficulty.
+
+Here are some examples screenshots of the widgets you can create:
