+dcaegen2-services-common.consulDeleteJob:
+This template generates a Kubernetes Job that runs when a
+DCAE microservice is deleted.  The Job deletes the Consul
+entry that contains the microservice's configuration.
+
+The template expects the full chart context as input.  A chart for a
+DCAE microservice references this template using:
+{{ include "dcaegen2-services-common.consulDeleteJob" . }}
+The template directly references data in .Values, and indirectly (through its
+use of templates from the ONAP "common" collection) references data in
+.Release.
+
+The microservice configuration data is loaded into Consul by an
+initContainer that is part of the Kubernetes Deployment for the microservice.
+See the documentation for dcaegen2-services-common.microserviceDeployment
+for more information.
