+Contributing
+============
+
+Contributing happens via "Pull requests" (PR) on github. Every PR needs to be
+reviewed before it can be merged and the Continuous Integration should be green.
+
+The PR has to be approved (and is often merged too) by one "code owner", either
+by the code owner who is responsible for the subsystem the PR belongs to or by
+two core developers or by Araq.
+
+See `codeowners <codeowners.html>`_ for more details.
