+# Instana Agent Installation
+
+See the official [documentation](https://docs.instana.io/quick_start/agent_setup/container/openshift/) for how to install the Instana agent on an OpenShift environment.
+
+# Robot Shop Deployment
+
+Have a look at the contents of the *setup.sh* and *deploy,sh* scripts, you may want to tweak some settings to suit your environment.
+
+Run the *setup.sh* script first, you will need the passwords for the developer and system:admin users.
+
+Once the set up is completed, run the *deploy.sh* script. This script imports the application images from Docker Hub into OpenShift, then it creates applications from those images.
+
+When the deployment has completed, to make Stan's Robot Shop accessible the web service needs to be updated.
+
+```bash
+oc edit svc web
+```
+
+Change *type* to **NodePort** when running on Minishift or **LoadBalancer** for regular OpenShift.
