+DMaaP Message Router utilizes an HTTP REST API to service all Publish
+and Consume transactions. HTTP and REST standards are followed so
+clients as varied as CURL, Java applications and even Web Browsers will
+work to interact with Message Router.Message Router uses AAF for user's
+authentication and authorization.
+
+General HTTP Requirements
+-------------------------
+
+A DMaaP Message Router transactions consists of 4 distinct segments,
+HTTP URL, HTTP Header, HTTP Body (POST) and HTTP Response. The general
+considerations for each segment are as follows and are required for each
+of the specific transactions described in this section.
+
+HTTP URL
+-------
+
+http[s]://serverBaseURL{/routing}{resourcePath}
+
+- The serverBaseURL points to DMaaP Message Router host/port that will service the request.
+
+- The resourcePath specifies the specific service, or Topic, that the client is attempting to reach
+
+HTTP Header
+-----------
+
+Specifies HTTP Headers, such as Content-Type, that define the parameters
+of the HTTP Transaction
+
+HTTP Body
+---------
+
+The HTTP Body contains the topic content when Publishing or Consuming.
+The Body may contain topic messages in several formats (like below) but
+it must be noted, that, except in very specific circumstances, messages
+are not inspected for content.
+
+
++-------------------------+-----------------------------------------------------------------------------------------------------------------+
+| Content-Type            |  Description                                                                                                    |
++=========================+=================================================================================================================+
+| text/plain              | Each line in the POST body is treated as a separate message. No partition key is specified, and therefore no    |
+|                         | order is guaranteed. This format is mainly for test, as messages are highly likely to be re-ordered when        |
+|                         | delivered through the Kafka cluster.                                                                            |
++-------------------------+-----------------------------------------------------------------------------------------------------------------+
+| application/json        | The payload maybe a single JSON object or a JSON array of JSON objects. Each object is handled as an individual |
+|                         | message..Note that use of this format may result in equivalent but altered JSON objects sent to consumers.      |
+|                         | That's because MR uses a standard JSON parser to read each object into memory before pushing the object to the  |
+|                         | Kafka system. At that point, the JSON object is re-written from the in-memory object. This can result in        |
+|                         | re-ordered fields or changes in whitespace. If you want to preserve JSON objects exactly,                       |
+|                         | use application/cambria. Recommended to follow the JSON format.                                                 |
++-------------------------+-----------------------------------------------------------------------------------------------------------------+
+
+Publishers
+-----------
+
+**Description**:Publishes data to Kafka server on the topic mentioned in the URL.
+Messages will be in the request body
+
+The MessageRouter service has no requirements on what publishers can put
+onto a topic. The messages are opaque to the service and are treated as
+raw bytes. In general, passing JSON messages is preferred, but this is
+due to higher-level features and related systems, not the MessageRouter
+broker itself.
