+#### Capture Output from a Docker Container
+
+You can capture output from the container, using the `::set-output` [workflow command](https://docs.github.com/en/actions/learn-github-actions/workflow-commands-for-github-actions) in GitHub Actions.
+Steps that execute following this step can access the output using the `${{ steps.<step_id>.outputs.<output_name> }}` syntax.
+For more information, see the [Contexts documentation](https://docs.github.com/en/actions/learn-github-actions/contexts) for GitHub Actions.
