+# Releasing previous major release
+
+## Preparation
+
+1. `git checkout v9`
+2. `git pull`
+3. `git checkout -b hotfix/v<next-patch-release-version>`
+4. Apply necessary hotfixes
+5. `cd scripts && yarn release:version --deferred --release-type patch --verbose && cd .. && git add . && git commit -m "Bump deferred version"`
+6. Add a new entry for the new version to the `CHANGELOG.md` file
+7. Trigger canary release via dispatching the workflow for `publish-canary`
+8. Test the canary release
+9. Merge `hotfix/v<next-patch-release-version>` into `v9`
+10. Observe the `publish-normal` job
+
+
+## Prepare major release branch for publishing
+
+1. Go to `https://github.com/storybookjs/storybook/settings/environments/1012979736/edit` (release environment) and add the major release branch (e.g. v9)
