+Handwired Atreus50
+==================
+
+This firmware is for a Handwired Atreus50 using an Arduino Pro Micro.
+
+## Pinout
+
+The following pins are used:
+- Columns 1-13: D4, D7, E6, B4, B5, B6, B2, B3, B1, F7, F6, F5, F4
+- Rows 1-4: D3, D2, D1, D0
+
+## Compiling and loading the firmware
+
+To build the firmware, run `make`.
+
+To flash the firemware onto the microcontroller, run `make avrdude`, and press the reset button.
