 ## Bump version
 
-1. Determine a new version number. Then set `VERSION` variable.
-
-    ```console
-    # Set VERSION and confirm it. It should not have "v" prefix.
-    $ VERSION=x.y.z
-    $ echo $VERSION
-    ```
-
-2. Make a branch to release
-
-    ```console
-    $ git neco dev "bump-$VERSION"
-    ```
-
-3. Edit `CHANGELOG.md` for the new version ([example][]).
-4. Commit the change and push it.
-
-    ```console
-    $ git commit -a -m "Bump version to $VERSION"
-    $ git neco review
-    ```
-
-5. Merge this branch.
-6. Add a git tag to the main HEAD, then push it.
-
-    ```console
-    # Set VERSION again.
-    $ VERSION=x.y.z
-    $ echo $VERSION
-
-    $ git checkout main
-    $ git pull
-    $ git tag -a -m "Release v$VERSION" "v$VERSION"
-
-    # Make sure the release tag exists.
-    $ git tag -ln | grep $VERSION
-
-    $ git push origin "v$VERSION"
-    ```
+1. Go to Actions on GitHub Web UI and select Release job.
+2. Run the workflow with an appropriate version number.
 
 GitHub actions will build and push artifacts such as container images and
 create a new GitHub release.
