+mailing list software, so you'll need to click the links below and

+### Contributions

+
+Spack is using a rough approximation of the [Git
+Flow](http://nvie.com/posts/a-successful-git-branching-model/)
+branching model. The ``develop`` branch contains the latest
+contributions, and ``master`` is always tagged and points to the
+latest stable release.
