          ## How to rebase

          If you're already using this image, upgrade with the following command:

          ```bash
          sudo bootc upgrade
          ```

          To switch to this image from another, type the following command in your terminal:

          ```bash
          sudo bootc switch ${{ inputs.latest-image-ref }}
          ```
          EOF
