 An auto-generated changelog really helps, even if you manually fill in the release notes!
 
+- **I want to define my own label-to-section mapping, how can I do it?**

+This is possible using either the ``add-sections`` or ``configure-sections``
+entry in ``.github_changelog_generator``. For example, to add a single new
+entry called "Maintenance" that will catch PRs tagged with your ``maintenance``
+label, you can add to ``.github_changelog_generator`` the line:
+```
+add-sections= {"maintenance":{"prefix":"**Project maintenance**","labels":["maintenance"]}}
+```
+A similar approach can be used via ``configure-sections`` to set all section
+properties (including adding new ones!).
