 Rally Deployments
 =================
 
-Before starting cluster benchmarking, its connection parameters
-should be saved in Rally database (deployment record).
+Rally needs to be configured to use an OpenStack Cloud deployment before it
+can benchmark the deployment.
 
-If there is no cluster, rally also can create it.
+To configure Rally to use an OpenStack Cloud deployment, you need create a
+deployment configuration by supplying the endpoint and credentials, as follows:
+
+.. code-block::
+
+    rally deployment create --file <one_of_files_from_this_dir> --name my_cloud
+
+
+If you don't have OpenStack deployments, Rally can deploy it for you.
+For samples of various deployments take a look at samples from
+**for_deploying_openstack_with_rally** directory.
