+Installing PNDA During Helm Chart Based DCAE Deployment
+=======================================================
+
+PNDA is integrated into ONAP as a component system of DCAE. It is possible to deploy PNDA as
+part of an ONAP OOM deployment on Openstack infrastructure. This is achieved by using a
+pnda-bootstrap container in kubernetes to deploy Openstack VMs and then install a PNDA cluster
+onto those VMs.
+
+Requirements
+------------
+
+PNDA deployment within ONAP requires the following:
+
+* Openstack based infrastructure. Follow the `PNDA guide <http://pnda.io/pnda-guide/provisioning/openstack/PREPARE.html>`_
+  for more information.
+* OOM / Helm template based installation of ONAP on Kubernetes.
+* Kubernetes and PNDA need to share the same Openstack network subnet.
+
+The dcae-pnda-bootstrap Helm chart currently deploys a PNDA cluster with the following resource
+requirements:
+
++--------------------+--------------------+--------------------+--------------------+
+|Node                |        CPU         |       RAM GB       |      Disk GB       |
++====================+====================+====================+====================+

++--------------------+--------------------+--------------------+--------------------+

++--------------------+--------------------+--------------------+--------------------+
+
+There are several parameters that need to be defined with values from your environment for a
+successful PNDA deployment within ONAP. These parameters can be grouped in separate files that
+are passed as parameters to helm install. With the following files, the command to install ONAP
+with PNDA would then look like this:
+
+::
+
+    helm install -f ~/pnda.yaml -f ~/pnda-openstack.yaml -f ~/pnda-pem.yaml local/onap -n dev --namespace onap
+
+
+
+``pnda.yaml``
+-------------
+
+This file contains settings to enable PNDA install and the evironment settings required by PNDA.
+
+::
+
+    pnda:
+      dcae-pnda-bootstrap:
+        enabled: true
+        pnda:
+          osUser: {guest-os-username}        # e.g. centos
+          nameserver: nn.nn.nn.nn            # IP address of a reachable nameserver
+          ntp: nn.nn.nn.nn                   # IP address of a reachable NTP server
+          apps:
