+# Release checklist
+# 1. Checkout the release branch (for a patch the current release branch, for a new minor version, create one):
+#      git checkout -b vXX.xx-release
+#    The -b is only necessary for creation (so remove it when doing a patch)
+# 2. Change the version in __init__.py and setup.py to the proper value.
+# 3. Commit these changes with the message: "Release: v<VERSION>"
+# 4. Add a tag in git to mark the release:
+#      git tag v<VERSION> -m 'Adds tag v<VERSION> for pypi'
+#    Push the tag and release commit to git: git push --tags origin vXX.xx-release
+# 5. Run the following commands in the top-level directory:
+#      rm -rf dist
+#      rm -rf build
+#      python setup.py bdist_wheel
+#      python setup.py sdist
+# 6. Upload the package to the pypi test server first:
+#      twine upload dist/* -r testpypi
+# 7. Check that you can install it in a virtualenv by running:
+#      pip install hf-doc-builder
+#      pip uninstall hf-doc-builder
+#      pip install -i https://testpypi.python.org/pypi hf-doc-builder
+#      It's recommended to check that there are no issues building the docs, 
+#      so try running a command like `doc-builder`
+# 8. Upload the final version to actual pypi:
+#      twine upload dist/* -r pypi
+# 9. Add release notes to the tag in github once everything is looking hunky-dory.
+# 10. Go back to the main branch and update the version in __init__.py, setup.py to the new version ".dev" and push to
+#     main.
