The quickstart guide should get anyone up and running with Flare using the downloadable version there is from them.
The second post has a partially recoded version of Flare to be friendly with Flex. I've worked on it more since then, and will continue to post updates as I get more and more working and cleaned up.
I hope this will be helpful, as Flare has some pretty cool things going for it (and some baffling choices also!).
