+4. For users with vanilla backstage instance, would need to integrate [`Auth`](https://backstage.io/docs/auth/) in to the instance:
+
+   - ```yaml title="app-config.yaml"
+     # see https://backstage.io/docs/auth/ to learn about auth providers
+     environment: development
+     providers:
+        # Plugin: GitHub

+           development:

+        ...
+     ```
+
+   - Integrate the [`SignIn`](https://backstage.io/docs/auth/#sign-in-configuration) component to be able to sign-in to the Backstage instance.
