It might be a good idea to have some docs on how this plugin works in the plugin's readme. And you can link to that with WikiUrl.

And it's most helpful if you write something quick and concise based generally around how you personally set up the settings and maybe some other ways if it can work if there are any. If you AI generate this it's probably going to be a massive hunk nobody wants to read.

Will do.

@Kuuuube Done. Docs here. I even edited the AI's draft a little bit ;). Thanks again
