 > **Starred Repositories**: Regardless of the chosen strategy, starred repositories are always mirrored to a separate organization (default: "starred") to keep them organized separately from your own repositories.

+> **Example Use Case**: With the "Preserve" strategy and overrides, you can:
+> - Mirror personal repos to `username-mirror` organization
+> - Keep `company-org` repos in their own `company-org` organization
+> - Override `community-scripts` to go to `community-mirrors` organization
+> - This gives you complete control while maintaining GitHub's structure as the default
