 Description
 ~~~~~~~~~~~
 
 The ONAP Integration Project provides a sample HEAT template that
 fully automates the deployment of ONAP using OOM as described in

 you need to do to deploy ONAP:

- source ./env/windriver/Integration-SB-00-openrc

+Exploring the Rancher VM
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+The Rancher VM that is spun up by this HEAT template serves the
+following key roles:
+- Installaion of the Rancher server
+- Hosts the /dockerdata-nfs/ NFS export shared by all the k8s VMs for persistent volumes
+- git clones the oom repo into /root/oom
+- git clones the integration repo into /root/integration
+- Creates the helm override file at /root/integration-override.yaml
+- Deploys ONAP using helm and OOM

+Deploying an Updated Docker Manifest
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Some late changes in the ONAP docker images did not make it in time
+for the Casablanca release.  Depending on the Use Case you are trying
+deploy, you may need to update the docker image manifest with certain
+newer docker image versions than what was shipped with ONAP Casablanca
+release.
+
+The ONAP integration repo contains a script that will apply the docker
+versions specified in a given manifest into the OOM helm chart
+definitions.
+
+To apply an updated manifest (on the Rancher VM):
+
+::
+
+   cd /root/integration/version-manifest/src/main/resources
+   cp docker-manifest.csv docker-manifest-custom.csv
+
+   # customize docker-manifest-custom.csv per your requirements
+
+   ../scripts/update-oom-image-versions.sh ./docker-manifest-custom.csv /root/oom/
+
+   cd /root/oom/kubernetes/
+   git diff # verify that the desired docker image changes are applied successfully
+   make all # recompile the helm charts
+
+After that you can update or redeploy ONAP OOM as described here:
