+There are a few basic ground-rules for contributors:
+
+1. **No `--force` pushes** or modifying the Git history in any way.
+1. **Non-master branches** ought to be used for ongoing work.
+1. **significant modifications** ought to be subject to an **internal pull-request** to solicit feedback from other contributors.
+1. Internal pull-requests to solicit feedback are *encouraged* for any other non-trivial contribution but left to the discretion of the contributor.
+1. Contributors should attempt to adhere to the prevailing style.
+
+## Releases
+
+Stick to semver: Major.Minor.Patch.
+
+## Changes to this arrangement
