+
+This example shows how to deploy a Java application with EAP 8.1 on OpenShift.
+
+## Prerequisites
+
+## Source Code
+
+The source code for the backend is hosted at https://github.com/jboss-eap-up-and-running/eap81-getting-started.git
+
+It is a simple application that uses JAX-RS to exposes HTTP endpoint.
+
+## Installation
+
+[source,options="nowrap"]
+----
+$ helm install eap81-app -f examples/eap81/getting-started/app.yaml ./charts/eap81
+----
+
+## Deployment
+
+Once the chart is installed, let's wait for the application to be built and deployed:
+
+[source,options="nowrap"]
+----
+$ oc get deployment/eap81-app -w
+NAME                      READY   UP-TO-DATE   AVAILABLE   AGE
+eap81-app                 0/1     1            0           27s
+...
+eap81-app                 1/1     1            1           5m29s
+----
+
+## Use the application
+
+Once the application is deployed on OpenShift, it can be accessed from the route `eap81-app`.
+Let's find the host that we can use to connect to this backend:
+
+[source,options="nowrap"]
+----
+$ oc get route eap81-app -o jsonpath="{.spec.host}"
+eap81-app-jmesnil1-dev.apps.sandbox.x8i5.p1.openshiftapps.com
+----
+
+This value will be different for every installation of the application.
+
+We can then query this application by calling its HTTP endpoint from the URL above.
+
+## Clean up
+
+The application can be deleted by running the command:
+
+[source,options="nowrap"]
+----
+$ helm delete eap81-app 
+release "eap81-app " uninstalled
+----
