A few newcomers in the Fedora Join matrix channel have noted that while we list the various channels, there isn't really a resource on how they are to be used. There's mailing list etiquette for example, but no real explanation on how to subscribe to a list and what to do to post. Similarly, even though Discourse and Matrix are quite intuitive perhaps short howtos with screenshots would be useful?

More thoughts:

• should any pages related to guidelines/etiquette also be moved to docs, if yes, where?
