wikit

wikit is another wiki engine suited for small teams. It’s written in Haskell with using Yesod Web Framework. It’s cross platform and was designed to be running as a desktop service application servicing wiki articles and providing some basic capabilities in terms of searching and storing data.

It’s perhaps most distinct feature is that it relies on backing Git distributed source control system. And keeps it’s articles in markdown format. Which makes it very easy to port out of the wiki and keep somewhere else if one would wish so, and vice versa, it allows to through bunch of existing documents in markdown format to be introduced into wiki and make available to your team.
