Add Github wiki

[bonelifer]

As a docker compose user, I think it'd be nice to have the info from this issue in a wiki article for people to see more widely. One less question for Discord: #865 (comment)

I agree, yes. I just haven't had time yet to update the docs. So I just keep answering the same question on discord over and over...

I don't really want to have yet another place to add docs. I think we should have a dedicated section about Docker in the Docs.

I misunderstood the request. My intent was not to create a GitHub wiki but just to add more Docker info into the existing docs
