+## About
+
+A simple voicemeeter-cli program. Offers ability to toggle, get and set parameters.
+
+## Use
+
+Toggle with `!` prefix, get by excluding `=` and set by including `=`. Mix and match arguments.
+
+You may pass the following optional flags:
+
+-   -v: (-verbose) to toggle console output.
+-   -i: (-interactive) to toggle interactive mode.
+-   -k: (-kind) to set the kind of Voicemeeter. Defaults to banana.
+
+for example:
+
+`powershell.exe .\CLI.ps1 -o -k "banana" -s "strip[0].mute", "!strip[0].mute", "strip[0].mute", "bus[2].eq.on=1", "command.lock=1"`
+
+Expected output:
+
+```
+Getting strip[0].mute
+strip[0].mute = 0
+Toggling strip[0].mute
+Getting strip[0].mute
+strip[0].mute = 1
+Setting bus[2].eq.on=1
+Setting command.lock=1
+```
+
+If running in interactive mode enter `<Enter>` to exit.
