-Examples of REST requests
-^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The following curl examples assume the server runs on localhost.
+
+Display version and retrieve default configuration
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+To get the current version and retrieve the default configuration and copy to a file:
+
+.. code-block:: bash
+
+    > curl http://localhost:8080/api/kloudbuster/version
+    7.1.1
+    > curl http://localhost:8080/api/config/default_config >default_config
+
+     ...
+
+
+Create a new Kloudbuster session
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Before running any benchmark, the first step is to create a new session:
+
+The body of the REST request msut have the following fields:
+
+.. code-block:: bash
+
+    {
+       'credentials': {'tested-rc': '<STRING>',
+                       'testing-rc': '<STRING>'},
+       'kb_cfg': {<USER_OVERRIDED_CONFIGS>},
+       'topo_cfg': {<TOPOLOGY_CONFIGS>},
+       'tenants_cfg': {<TENANT_AND_USER_LISTS_FOR_REUSING>},
+       'storage_mode': true|false
+    }
+
+List of fields and content:
+
+- credentials (mandatory)
+- tested-rc (mandatory) contains the openrc variables (string containing the list of variables separated by \n)
+- testing-rc (optional) only needed in case of dual cloud testing (HTTP only)
+- kb_cfg (mandatory) a string containing the Kloudbuster configuration to use (json)
+- topo_cfg (optional) a string containing the topology configuration (json)
+- tenants_cfg (optional) a string containing the list of tenants and users to use (json)
+- storage_mode (mandatory) true for storage benchmark, false for HTTP benchmark
+
+
+Example of configuration:
+
+.. code-block:: bash
+
+    # Content of a standard openrc file that we store in a variable
+    OPENRC="export OS_CACERT=/root/openstack-configs/haproxy-ca.crt

+    export OS_USER_DOMAIN_NAME=default
+    export OS_IDENTITY_API_VERSION=3"

+    KBCFG="{client:{storage_stage_configs:{ vm_count: 1, disk_size: 50, io_file_size: 1},
+    storage_tool_configs:{[description: 'Random Read', mode: 'randread', runtime: 30,
+    block_size: '4k', iodepth: 4]}}}"

+    BODY="{'credentials': {'tested-rc': $OPENRC},
+           'kb_cfg': $KBCFG,
+           'storage_mode': true}"
+
+Create the Kloudbuster session with above configuration:
+
+.. code-block:: bash
+
+    > curl -H "Content-Type: application/json" -X POST -d "$BODY" http://localhost:8080/api/config/running_config
+
+Note that this request only updates the running configuration and does not start any benchmark.
+It will return a session ID that needs to be passed to subsequent REST requests.
+
+Start a storage benchmark using the running configuration
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+SESSION_ID is the id returned from the /api/config/running_config POST request.
