+The faders IDs are from left to right 0 - 7 and the knob IDs are 16 - 23. To
+map spotify to the leftmost fader you would type
 
 ```sh
 [fader 0]
 application = spotify
 ```
 
+To map Firefox to the leftmost knob you would type
+
+```sh
+[knob 16]
+application = Firefox
+```
+
+You can map any pipewire node to any fader or knob, i.e. not only applications, but
+also for example output and devices:
+
+```sh
+[fader 6]
+application = alsa_output.usb-Beyerdynamic_FOX_5.00-00.analog-stereo
+
+[fader 22]
+application = alsa_input.usb-Beyerdynamic_FOX_5.00-00.mono-fallback.3
+```

 You can force reconfiguration with `cycle` button from midiKONTROL2. This is
 required if you open up a application after starting midi-mixer
