+Core guidelines
+~~~~~~~~~~~~~~~
+While we welcome new contributors, reviewer capacity is limited. Therefore,
+following these core guidelines is essential:
+
+* Every pull request (PR) should address one or more open issues. The PR should
+  be outlined in the issue discussion.
+* GSoC: For Google Summer of Code, we invite applications only from those with
+  significant PV modeling experience and who are motivated to join the pvlib
+  maintenance teams
+* pvlib-python is an advanced scientific modeling toolbox. A background
+  in solar energy and/or experience in pvlib-python is required to
+  address some issues effectively. It is not always clear which issues
+  fall into this bucket. Don't be offended if maintainers close your PR for
+  this reason.
+* Maintainers reserve the right to close PRs that do not comply with the
+  contributing guidelines.
