Manual:Wiki_family is rather a mess.
I’d like help improve it a bit and have started an outline of what I think should be there. I was wondering if people could have a read of the basic principles section and see if it makes sense. My idea next is to create sections on that page for each of the top-level numbered steps in that overview, and elaborate on them.
There’s some confusing and wrong information on that page, but there’s also some required confusion that results from the disparity between the way the WMF manage sites and the way most sysadmins are likely to; it’d be nice to make these things clearer, and for everyone do things the same way unless there are actual reasons (and not just misunderstandings).
