 ## 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.
+- You can solder Restore key (connector pin "I") paraller to some other pin. I soldered "I" and "G" to Arduino pin A8. (this is actually not needed, because there is one free pin left)
+- You can also connect LED of C64 to VCC/GND of Arduino. I used 220ohm resistor.
