I think maybe changing it to "install" might be good, because it does take someone with basic sysadmin skills to set up anyway.

I'd also consider putting the "find a community" stuff at the top too, since that's probably the first thing you'd want people to look at (and they can install the software if they don't find one).

I think this indicates a problem in your marketing on that site. The first time I looked at the site I thought the same thing: "why is there a download? give me the wikis!"
