+### Conclusion
+
 That's it! We created an app that handles both authentication and user
 permissions without any back-end set up. To test the how the `/profile` route
 permissions work, try navigating to `/profile` directly in the browser. As a
 guest user the link to that view will not be displayed, instead you will be
 redirected to the `restricted` view.

+Using the concepts covered in this example you are now ready to start writing
+your own GoAngular app using [$goUsers](../users.md) and auth with [$goConnection](../connection.md).
