+DMaaP connection objects
+========================
+
+DMaaP connection objects are JSON objects that:
+
+1. Components should expect at runtime in their application
+ configuration and is to be used to connect to the appropriate DMaaP
+ feed or topic.
+2. Developers must provide through the command-line argument
+ ``--dmaap-file`` to test their component with manually provisioned
+ feeds and topics.
+
+This page is a reference to the specific structure that each type of
+DMaaP stream requires.
+
+Note for #1 that components should expect the entire object with all
+properties at runtime where the default will be ``null`` unless
+specified otherwise.
+
+Note for #2 that developers are not required to provide the entire
+object. The required properties will be labeled with “*required as
+input*”.

+
+Developers are recommended to use ``username`` and ``password`` since
+this is the recommended security practice.
+
+Note that the dcae-cli will construct the ``delivery_url`` when
+deploying the component since this can only be known at deployment time.
