Dokuwiki has been my go-to solution for docs everywhere I've been for the past ten years or so unless they already have a (usable) wiki in place. Trivial to set up. Trivial to migrate to, and from (should you ever need to). Doesn't need a database. There are lots of plugins available and it's sooo easy to write plugins for. Even if you hate PHP.
