+How to make a release
+=====================
+
+- Sync local `master` and `develop` with Github
+  - `for x in master develop; git checkout $x; git pull`
+- On `develop` branch
+  - Update `src/iminuit/version.py` to the release version
+    - For a beta release, add `.betaN`, where N is a number >= 0
+    - For a release candidate, add `.rcN`
+  - Run `python3 doc/update_changelog.py` or update `doc/changelog.rst` manually
+    - Check the output if you used the script
+- Merge `develop` into `master`
+  - Every push to `master` triggers building wheels, uploading to PyPI, and tagging/publishing on GitHub
+  - If there are problems with the wheels, commit fixes to `develop`, then merge again into `master`
+  - Note: Upload to PyPI uses API tokens configured in PyPI and Github "Secrets"
+
+- conda-forge should pick up our release automatically and generate conda packages
