 ## Overview
 
 This application has three submenu items:
-* Match
+* Measure
+- Use the left and right button to move around pins. 
+- Use the up and down button to adjust the depth of the bitting. 
 * Config
+- There are currently two key formats to choose from: Kwikset (KW1) and Schalage (SC4). 
+- The key name is reserved for future development of the file saving feature.
 * About
+- Key Maker App 0.1
+- Based on Derak Jamison's Skeleton App
+- Project channel: https://discord.gg/BwNar4pAQ9
