+DMaaP Client based API
+======================
+
+ONAP Gerrit repo: \ https://gerrit.onap.org/r/#/admin/projects/aai/event-client
+
+This is a thin API library based on the DMaaP Client, and exposes
+methods that can be used to publish and consume JSON messages to/from a
+DMaaP topic.
+
+Importing the library
+=====================
+
+To add the Event Bus Client Library to your project simply include the
+following dependencies in your project's pom.xml. Note that
+the httpclient dependency may be required in your project pom if you are
+also depending on AJSC artifacts, as they use an earlier version of
+the httpclient which may overwrite the later version required by the
+library.
+
+<dependency>
+
+<groupId>org.onap.aai.event-client</groupId>
+
+<artifactId>event-client-dmaap</artifactId>
+
+<version>1.2.0-SNAPSHOT</version>
+
+</dependency>
+
+<!-- This dependency is required if you also have AJSC dependencies -->
+
+<dependency>
+
+<groupId>org.apache.httpcomponents</groupId>
+
+<artifactId>httpclient</artifactId>
+
+<version>4.5.2</version>
+
+</dependency>
+
+<!-- This dependency is required if you also have AJSC dependencies -->
+
+**Note** - In order to retrieve all of the client's transitive
+dependencies you may need to configure your maven settings.xml with the
+ONAP repositories.
+
+Publishing
+==========
+
+Here is an example of how to use the client to publish a message to the
+DMaaP topic.
+
+DMaaPEventPublisher eventPublisher = new DMaaPEventPublisher(host,
+topic, username, password);
+
+try {
+
+int result = eventPublisher.sendSync(partition, messages);
+
+// result should equal number of messages supplied to sendSync
+
+} catch (...) {
+
+} finally {
+
+List<String> unsentMessages = eventPublisher.closeWithUnsent()
+
+// Handle unsent messages
+
+}
+
+**host** - The host URL to use to connect to the DMaaP topic, in the
+form of <host:port>.
+
+**topic** - The topic name to publish to. This must be an existing DMaaP
+topic.
+
+**username** - The MechID of the calling application.
+
+**password** - The password for the MechID.
+
+**partition** - The partition to publish the message to.
+
+**message** - A List of JSON String messages to publish as a batch.
+
+Consuming
+---------
+
+Here is an example of how to use the client to consume messages from the
+UEB.
+
+try {
+
+DMaaPEventConsumer consumer = new DMaaPEventConsumer(host, topic,
+username, password, consumerGroup, consumerId)
+
+Iterable<String> messages = consumer.consume();
+
+for(String message : messages) {
+
+// process message
+
+}
+
+} catch(...) {}
+
+**host** - The host URL to use to connect to the DMaaP topic, in the
+form of <host:port>.
+
+**topic** - The topic name to consume from. This must be an existing
+topic.
+
+**username** - The MechID of the calling application.
+
+**password** - The password for the MechID.
+
+**consumerGroup** - The name of the consumer group this consumer is part
+of.
+
+**consumerId** - The unique id of this consumer in its group.
+
+Creating Topics and Authentication
+==================================
