-- Helm charts for ph and dh
-- New container to do Consul k-v storage and service reg
-- Bootstrap container no longer deploys ph and dh
-- Healthcheck looks for ph and dh as Helm deployments
-- Updated/added licensing information

+# DCAE Consul Loader Container
+
+The Dockerfile in this directory builds an image that can be used to spin up a container (typical a Kubernetes init container) that can load
+service registrations and key-value pairs into a Consul instance.   This capability supports moving certain DCAE platform components from
+deployment using a Cloudify blueprint and the ONAP Kubernetes plugin to a Helm-based deployment.  An init container can do the Consul
+setup previously handled by the ONAP Kubernetes plugin and the ONAP DCAE bootstrap script.
+
+The entrypoint for the container is the script `consul_store.sh`.  See the documentation for `consul_store.sh` to see how to provide arguments to the script
+as well as how to use environment variables to set the Consul API protocol, host, and port.
+
+Note that the container runs the script to completion.  It is not intended to be a long-running service.
