 ====================
 
 Under construction...
+
+
+Creating an ONAP deployment instance requires creating base configuration on the
+host node and then deploying the runtime containers.
+
+The following is an example of creating the first deployed instance in a K8s
+cluster. The name given to the instance is 'dev1'. This will serve as the
+Namespace prefix for each deployed ONAP component (ie. dev1-mso).
+
+  1. oom/kubernetes/config/createConfig.sh -n dev1
+
+  2. oom/kubernetes/oneclick/createAll.bash -n dev1
+
+To delete the runtime containers for the deployed instance, use the following:
+
+  3. oom/kubernetes/oneclick/deleteAll.bash -n dev1
+
+Note that deleting the runtime containers does not remove the configuration
+created in step 1.
+
+
+To deploy more than one ONAP instance within the same Kubernetes cluster, you
+will need to specify an Instance number. This is currently required due to the
+use of NodePort ranges. NodePorts allow external IP:Port access to containers
+that are running inside a Kubernetes cluster.
+
+Example if this is the 2 instance of an ONAP deployment in the cluster:
+
+  1. oom/kubernetes/config/createConfig.sh -n test
+
+  2. oom/kubernetes/oneclick/createAll.bash -n test -i 2
