+## About
+
+A simple demonstration showing how to sync OBS scene switches to Voicemeeter states. The script assumes you have connection info saved in
+a config file named `config.toml` placed next to `main.go`. It also assumes you have scenes named `START` `BRB` `END` and `LIVE`.
+
+A valid `config.toml` file might look like this:

+```toml
+[connection]
+Host="localhost"
+Port=4455
+Password="mystrongpass"

+## 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 an optional flag -kind to set the kind of Voicemeeter. Defaults to banana.
+
+You may pass an optional flag -delay to set a delay on the getters. Defaults to 20ms.
+
+for example:
+
+`go run .\main.go -kind=potato -delay=18 strip[0].mute=0 strip[0].mute !strip[0].mute strip[0].mute bus[0].gain=-8.8 command.lock=1`
+
+Expected output:
+
+```
+Logged into Voicemeeter potato
+Running command strip[0].mute=0
+Value of strip[0].mute is: 0
+Toggling strip[0].mute
+Value of strip[0].mute is: 1
