+## Building
+- Solder all keyboard connector pins to Arduino Pro Micro.
+- You can solder Restore key (connector pin "I") paraller to some other pin. I soldered "I" and "G" to Arduino pin A8.
 
+## Firmware/flashing
+- Download Soarer controller firmware: https://geekhack.org/index.php?topic=50437.0
+- Install Arduino IDE
+- Connect RST to GND couple of times to get Arduino Pro Micro to programming mode (notice that com-port is different in programming mode in Windows)
+- Flash firmware
+```
+& "C:\Program Files (x86)\Arduino\hardware\tools\avr/bin/avrdude" -C"C:\Program Files (x86)\Arduino\hardware\tools\avr/etc/avrdude.conf" -v -p m32u4 -c avr109 -P COM5 -b 57600 -U flash:w:firmware\Soarer_Controller_v1.20_beta4_atmega32u4.hex:i
+```
+
+
+
+## Setup
+Download configfile. Check pin order to match your setup.
+```
+.\scas C64_matrix.sc C64_matrix.bin
+.\scwr C64_matrix.bin
+```
+
+## Pins I used
