+# Release process for `dev.py`
+
+## Introduction
+
+Example `version`
+
+- 1.8.dev0 # development version of 1.8 (release candidate 1)
+- 1.8rc1 # 1.8 release candidate 1
+- 1.8rc2.dev0 # development version of 1.8 release candidate 2
+- 1.8 # 1.8 release
+- 1.9.dev0 # development version of 1.9 (release candidate 1)
+
+## Process
+
+- Update and review `CHANGELOG.md`:
+
+      gem install github_changelog_generator
+      github_changelog_generator -u scientific-python -p dev.py --since-tag=<last tag>
+
+- Update `version` in `pyproject.toml`.
+
+- Commit changes:
+
+      git add pyproject.toml CHANGELOG.md
+      git commit -m 'Designate <version> release'
+
+- Add the version number (e.g., `1.2.0`) as a tag in git:
+
+      git tag -s [-u <key-id>] v<version> -m 'signed <version> tag'
+
+  If you do not have a gpg key, use -u instead; it is important for
+  Debian packaging that the tags are annotated
+
+- Push the new meta-data to github:
+
+      git push --tags origin main
+
+  where `origin` is the name of the `github.com:scientific-python/dev.py`
+  repository
+
+- Review the github release page:
+
+      https://github.com/scientific-python/dev.py/releases
+
+- Publish on PyPi:
+
+      git clean -fxd
+      pip install flit
+      flit build
+      flit publish
+
+- Update `version` in `pyproject.toml`.
+
+- Commit changes:
+
+      git add pyproject.toml
+      git commit -m 'Bump version'
+      git push origin main
