+## Requirements
+
+-   [OBS Studio](https://obsproject.com/)
+-   [OBS Python SDK for Websocket v5](https://github.com/aatikturk/obsws-python)
+
+## About
+
+A simple demonstration showing how to sync XAir states with OBS scene switches. The script assumes you have OBS connection info saved in
+a config file named `config.toml` placed next to `__main__.py`. 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"
+```
+
+## Use
+
+Change the xair ip argument from `mixer.local` to the ip of your xair mixer. Run the code and switch between scenes in OBS.
