+# Helm Example
+
+This example will deploy the [Kubernetes sample guestbook](https://github.com/kubernetes/examples/tree/master/guestbook/) application
+using kustomize. The app will be deployed into the `fleet-kustomize-example` namespace.
+
+The application will be customized as follows per environment:
+
+* Dev clusters: Only the redis leader is deployed and not the followers.
+* Test clusters: Scale the front deployment to 3
+* Prod clusters: Scale the front deployment to 3 and set the service type to LoadBalancer
