+Danube OpenStack User Guide
+============================
+
+OpenStack is a cloud operating system developed and released by the
+`OpenStack project <https://www.openstack.org>`_.  OpenStack is used in OPNFV
+for controlling pools of compute, storage, and networking resources in a Pharos
+compliant infrastructure.
+
+OpenStack is used in Danube to manage tenants (known in OpenStack as
+projects),users, services, images, flavours, and quotas across the Pharos
+infrastructure.The OpenStack interface provides the primary interface for an
+operational Danube deployment and it is from the "horizon console" that an
+OPNFV user will perform the majority of administrative and operational
+activities on the deployment.
+
+OpenStack references
+--------------------
+
+The `OpenStack user guide <http://docs.openstack.org/user-guide>`_ provides
+details and descriptions of how to configure and interact with the OpenStack
+deployment.This guide can be used by lab engineers and operators to tune the
+OpenStack deployment to your liking.
+
+Once you have configured OpenStack to your purposes, or the Danube
+deployment meets your needs as deployed, an operator, or administrator, will
+find the best guidance for working with OpenStack in the
+`OpenStack administration guide <http://docs.openstack.org/user-guide-admin>`_.
+
+Connecting to the OpenStack instance
+------------------------------------
+
+Once familiar with the basic of working with OpenStack you will want to connect
+to the OpenStack instance via the Horizon Console.  The Horizon console provide
+a Web based GUI that will allow you operate the deployment.
+To do this you should open a browser on the JumpHost to the following address
+and enter the username and password:
+
+
+  http://{Controller-VIP}:80/index.html>
+  username: admin
+  password: admin
+
+Other methods of interacting with and configuring OpenStack,, like the REST API
+and CLI are also available in the Danube deployment, see the
+`OpenStack administration guide <http://docs.openstack.org/user-guide-admin>`_
+for more information on using those interfaces.
