+## Wireing
+
+To connect the ESP32 to the FC:
+- wire up +5V and GND
+- TX from FC to ESP RX pin 17
+- RX from FC to ESP TX pin 23
+
+Thanks for testing! 😄 👍
+
+## FC settings
+
+Backup your FC settings, flash the current [testing version of INAV](https://github.com/mistyk/inavradar-ESP32/releases).
+
+Dump your backup back into the cli.
+
+Activate MSP on the corrosponding UART, the speed is 57600.

 ## Commands
 
-After the firmware is flashed on the devices you should see 'No FC' (or the name of the UAV) on the opposing display.
-If only the bottom line with TX and RX is showing, something is not working correctly, please open a serial terminal (Windows e.g. [PuTTy](https://www.chiark.greenend.org.uk/~sgtatham/putty/latest.html)). Reset the device connected to the terminal and send us a copy of the output.
