+
+Now I will turn this into a proper library and clean up what the AI made because there are still some things I want different. I first started off removing all of my code and reducing it down to just what's needed to run the screen with the library. Then I replaced all variables with generic ones instead of using my structs and bringing confusion
+```cpp
+  // Update menu button states
+  menu.setButtons(buttonDown, buttonRight, buttonUp);
+```
+Instead of 
+```cpp
+menu.setButtons(JoystickDataHard.LXD, buttonRight, JoystickDataHard.LXU);
+```
+
+I also removed all unused graphics from the file reducing it down to 65 lines instead of 1165 lines. Then I added some documentation to everything using DoxyGen.
+![alt text](image-12.jpg)
+Doxygen makes it so you can hover functions and see what they do and what all parameters are.
