 A simple voicemeeter-cli program. Offers ability to toggle, get and set parameters.
 
+## Install
+
+First build and install it with `go install` (skip this step if using binary from [Releases](https://github.com/onyx-and-iris/voicemeeter/releases))
+
 ## 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. Defaults to false.
+-   -v: (-verbose) to toggle console output.
+-   -i: (-interactive) to toggle interactive mode.
 -   -k: (-kind) to set the kind of Voicemeeter. Defaults to banana.
 -   -d: (-delay) to set a delay on the getters. Defaults to 20ms.
 
 for example:
 
-`go run .\main.go -v -k=potato -d=25 strip[0].mute=0 strip[0].mute !strip[0].mute strip[0].mute bus[0].gain=-8.8 command.lock=1`
+`vm-cli.exe -v -k=potato -d=25 strip[0].mute=0 strip[0].mute !strip[0].mute strip[0].mute bus[0].gain=-8.8 command.lock=1`
 
 Expected output:
