 ## Configuration
-You will need serial number of the meter, it can be found on the meter label itself 
+1. Enable SPI in raspi-config.
+2. Install WiringPi from https://github.com/WiringPi/WiringPi/
+3. Set meter serial number and production date in `cc1101.c`, it can be found on the meter label itself:
