 ## About
 
-A basic command-line interface
+A simple voicemeeter-cli script. Offers ability to toggle, get and set parameters.
 
 ## Use
 
-```console
-Voicemeeter CLI
+Toggle with `!` prefix, get by excluding `=` and set by including `=`. Mix and match arguments.
 
-Usage:
-  CLI.ps1 [-interactive] [-kind <basic|banana|potato>] [-script <command1>, <command2>, ...]
+You may pass the following optional flags:
 
-Options:
-  -help               Display this help message.
-  -interactive        Start in interactive mode.
-  -kind <type>        Specify the Voicemeeter type (basic, banana or potato). Default is banana.
-  -script <commands>  Provide a list of commands to execute in sequence.
-
-Commands can be of the form:
-  Parameter=Value     Set a parameter to a specific value.
-  !Parameter          Toggle a boolean parameter.
-  Parameter           Get the current value of a parameter.
-```
+-   -o: (-output) to toggle console output.
+-   -i: (-interactive) to toggle interactive mode.
+-   -k: (-kind) to set the kind of Voicemeeter. Defaults to banana.
+-   -s: (script) a string array, one string for each command.
 
 for example:
 
 ```powershell
-.\CLI.ps1 -script strip[0].mute, !strip[0].mute, strip[0].mute, bus[2].eq.on=1, command.lock=1
+.\CLI.ps1 -o -k "banana" -s "strip[0].mute", "!strip[0].mute", "strip[0].mute", "bus[2].eq.on=1", "command.lock=1"
 ```
 
-should produce the output:
+Expected output:
 
-```console
-strip[0].mute = 1
-Toggled strip[0].mute to 0
+```powershell
+Getting strip[0].mute
 strip[0].mute = 0
-Set bus[2].eq.on=1
-Set command.lock=1
-```
+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 press `<Enter>` to exit.
