+## Release setup
+
+To release a new version:
+
+```sh
+make release bump=$$VERSION_PART_TO_BUMP$$
+```
+
+#### How to bumpversion
+
+The version format for this repo is `{major}.{minor}.{patch}` for stable, and
+`{major}.{minor}.{patch}-{stage}.{devnum}` for unstable (`stage` can be alpha or beta).
+
+To issue the next version in line, specify which part to bump,
+like `make release bump=minor` or `make release bump=devnum`.
+
+If you are in a beta version, `make release bump=stage` will switch to a stable.
+
+To issue an unstable version when the current version is stable, specify the
+new version explicitly, like `make release bump="--new-version 4.0.0-alpha.1 devnum"`
