 3. **Configuration**: Adjust radio parameters (frequency, bandwidth,
    master/client mode, IP addresses) as described in the
    [original NPR documentation](https://cdn.hackaday.io/files/1640927020512128/NPR70_introduction_EN_v3.6.pdf)
 4. **Connect**: Plug in Ethernet and power, connect antenna, and start experimenting
 
+Basic settings to check (more details in the original NPR documentation):
+
+* `display config`: show current configuration
+* `set <param> <value>`: store value to the given parameter
+* `save`: saves current configuration into the EEPROM
+* `radio on`/`radio off`: turn RF on or off
+* `reboot`: reboot the FW
+
+You have to set your callsign, frequency and modulation. Rest of the parameters
+is up to you and your setup.
+
+```
+set callsign AB1CDE
+set frequency 434.200
+set modulation 22
+```
