Driver Installation =================== Windows 8.1 or lower ******************** Before we get started with any remapping or programming, you'll need the driver for the keypad installed. `Adafruit Drivers `_ You can install all of the drivers if you'd like, but only the "Feather 32u4, Feather M0, Feather M0 Express..." option is necessary. For keypads purchased before 3/15/18 ------------------------------------ `Arduino Leonardo Drivers `_ Download and extract the zip to your desktop and open "dpinst-amd64.exe." Follow the wizard and say yes when it asks. That's it! Windows 10, Mac, and Linux ************************** No driver installation required. You're done, great job!
