+#### Create the builder image
+The following command will create a builder image named golang-centos7.
+```
+$ oc new-app https://github.com/nmasse-itix/golang-s2i.git --name=golang-centos7
+```
+
+#### Creating the application image
+The application image combines the builder image with your applications source code, which is served using whatever application is installed via the *Dockerfile*, compiled using the *assemble* script, and run using the *run* script.
+The following command will create the application image:
+```
+$ oc new-app --strategy=source --context-dir=test/test-app --name golang-centos7-app golang-centos7~https://github.com/nmasse-itix/golang-s2i.git
+```
+Using the logic defined in the *assemble* script, s2i will now create an application image using the builder image as a base and including the source code from the test/test-app directory.
+
+#### Running the application image
+Running the application image is as simple as invoking the "oc new-app" command:
+```
+$ oc expose service golang-centos7-app
+$ oc get route golang-centos7-app
+```
+The application, which consists of a simple static web page, should now be accessible at the url shown on last command (oc get route).
