+#### Running on OpenShift
+
+First, make sure you have an instance of OpenShift setup and are logged in using `oc login`.
+
+Then create a new project using the `oc` commands
+
+`oc new-project fun-node-fun`
+
+For this example, you will also need a postgres db running on your OpenShift cluster.
+
+`oc new-app -e POSTGRESQL_USER=luke -ePOSTGRESQL_PASSWORD=secret -ePOSTGRESQL_DATABASE=my_data centos/postgresql-10-centos7 --name=my-database`
+
+Then run `npm run openshift` to deploy your app
+
+Then you can navigate to the newly exposed route, something similar to "http://nodejs-rest-http-crud-boosters.192.168.99.100.nip.io/",  this will probably be different based on your OpenShift IP address
