-### Set scopes for the authentication token
-
-The `scope` input allows limiting registry credentials to a specific repository
-or namespace scope when building images with Buildx.
-
-This is useful in GitHub Actions to avoid overriding the Docker Hub
-authentication token embedded in GitHub-hosted runners, which is used for
-pulling images without rate limits. By scoping credentials, you can
-authenticate only where needed (typically for pushing), while keeping
-unauthenticated pulls for base images.
-
-When `scope` is set, credentials are written to the Buildx configuration
-instead of the global Docker configuration. This means:
-* Authentication applies only to the specified scope
-* The default Docker Hub credentials remain available for pulls
-* Credentials are used only by Buildx during the build
-
-> [!IMPORTANT]
-> Credentials written to the Buildx configuration are only accessible by Buildx.
-> They are not available to `docker pull`, `docker push`, or any other Docker
-> CLI commands outside Buildx.
-
-> [!NOTE]
-> This feature requires Buildx version 0.31.0 or later.

-        with:
-          push: true
-          tags: myorg/myimage:latest

-
-In this example, base images are pulled using the embedded GitHub-hosted runner
-credentials, while authenticated access is used only to push `myorg/myimage`.
