I got started because in the Flask docs section, they had a .mobi file to download and read on my Kindle. (They also have PDF, ePub, zipped-html). I wish more projects had such excellent documentation, including a lot of the Flask extensions that I find on github.
Cool thanks for the heads up. Might have to check that out, since I'm still searching for how I'm going to manage my websocket connections to a server....
