-How to make a release
-=====================
+# How to make a release
 
 - Sync local `main` and `develop` with Github
+
   - `for x in main develop; git checkout $x; git pull`
+
 - On `develop` branch
+
   - Update version in `pyproject.toml`
     - 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
+  - If necessary, update ROOT version in `doc/conf.py`, see instructions there
+
 - Merge `develop` into `main`
+
   - Every push to `main` 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 `main`
   - Note: Upload to PyPI uses API tokens configured in PyPI and Github "Secrets"
