mix pugs setup guide

We have a mix-4v4 pug channel that is barely being used. I think this is due to the fact that nearly no team knows how to setup a channel in their own discord server. I've seen RKW doing it so apparently it still works, but no one knows how to set it up and there is no information to find in the info-and-rules channel IN the pug category. if we already have that channel, why not put a message in there that tells you how to set it up?
