+# Kubernetes Guestbook application example
+
+This is an example containerized Guestbook application originally authored by the Kubernetes community for use in their own tutorial. The application's Kubernetes deployment manifests copied over from the Kubernetes source [repo](https://github.com/kubernetes/examples/tree/master/guestbook) are contained in the `deploy` directory. 
+
+The Guestbook application consists of a web front end along with primary and secondary Redis containers for storage, all deployed with Kubernetes. For more information about the application and accessing its source code, see the [Kubernetes tutorial](https://kubernetes.io/docs/tutorials/stateless-application/guestbook/) and their [examples repo](https://github.com/kubernetes/examples/tree/master/guestbook).
