Third-party repos: link to docs
In an effort to be distro-agnostic, the third party repos page doesn't include specific details of what's included in the repos themselves. Unfortunately this is not a great experience for users - how can people decide to opt into some repos if they don't know what they contain?
A partial solution might be to make "select external sources" into a configurable link. In Fedora's case, this would like to a docs page with a list of the repos that are included.
It's still not a fantastic experience, but it would be better than what we currently have.
