   This template generates a Kubernetes init containers common template to enable applications to provision
-  DMaaP feeds (on Data Router), with associated authorization.
-  DMaap Bus Controller endpoints are used to provision:
-
-  - Feed on DR, with associated user authentication.
+  DMaaP feeds (on Data Router) for DCAE microservices, with associated authorization.
+  DMaap Data Router (DR) endpoints are used to provision:
+  - Feeds on DR, with associated user authentication.
+  - Subscribers to feeds on DR, to provide DR with username, password, and URL needed to deliver
+    files to subscribers.
 
   common.dmaap.provisioning.initContainer:
-  This template make use of Dmaap Bus Controller docker image to create resources on Dmaap Data Router
-  microservice, with the help of dbc-client.sh script it makes use of Bus Controller API to create Feeds.
-  If the resource creation is successful via script response is logged back at particular location with
-  appropriate naming convention.
-
-  More details can be found at :
-  (https://wiki.onap.org/pages/viewpage.action?pageId=103417564)
+  This template creates an initContainer with some associated volumes.  The initContainer
+  (oom/kubernetes/dmaap-datarouter/drprov-client) runs a script (drprov-client.sh) that uses the
+  DR provisioning API to create the feeds and subscribers needed by a microservice.  The script
+  updates the microservice's configuration to supply information needed to access the feeds. The
+  configuration information comes from two volumes that are created by the dcaegen2-services-common
+  templates.
+  - app-config-input: comes from a configMap generated from the microservice's values.yaml file.
+    It may contain references to environment variables as placeholders for feed information that
+    will become available after feeds are provisioned.
+  - app-config: this template will copy the configuration file from the app-config-input volume,
+    replaced the environment variable references with the actual values for feed information, based
+    on data returned by the DR provisioning API.
 
   The template directly references data in .Values, and indirectly (through its
   use of templates from the ONAP "common" collection) references data in .Release.
