+## 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"
+
+```
