### Request type Enhancement ### What needs to get done We do have a [Plugins reference page](https://documentation.ubuntu.com/rockcraft/en/latest/reference/plugins/), but no _explanation page_ exists for Plugins. It would be great to have a dedicated _explanation page_ for Plugins. ### Documentation location _No response_ ### Additional information * This is a request for a new explanation page about Plugins * It would also be great to have this new page linked from different parts of the documentation
