+Riddle uses the "git-flow":http://jeffkreeftmeijer.com/2010/why-arent-you-using-git-flow/ process for development. The "master" branch is the latest released code (in a gem). The "develop" branch is what's coming in the next release. (There may be occasional feature and hotfix branches, although these are generally not pushed to GitHub.)
+
+When submitting a patch to riddle, please submit your pull request against the "develop" branch.
