+
+Things that are possible with this CLI:
+
+*Fade out main LR all the way to -∞*
+
+```console
+xair-cli main fadeout
+```
+
+*enable phantom power and set the gain to 28dB for strip 09*
+```console
+xair-cli headamp 9 phantom on
+
+xair-cli headamp 9 gain 28
+```
+
+*adjust strip 09 send level to bus 5*
+```console
+xair-cli strip send 9 5 -- -18.0
+```
+
+*rename bus 01 to 'vocal mix'*
+```console
+xair-cli bus 1 name 'vocal mix'
+```
