-- `type`: message type, consisting of hyphenated classes (e.g. `yt-moderator` or `tw-vip-color#A1B2C3` etc, see below in the "Customization" section of this README). This field defines how the message will be styled when being rendered on the frontend.
+- `type`: message type, consisting of `^`-delimited classes (e.g. `yt^moderator` or `tw^vip^color#A1B2C3` etc, see below in the "Customization" section of this README). This field defines how the message will be styled when being rendered on the frontend.
 - `timestamp`: an ISO 8601 **UTC** timestamp string denoting when the message was sent. The only recommended format (in strftime syntax) is `%Y-%m-%dT%H:%M:%SZ`.
