+Using Mistral with OpenStack
+============================
+
+The **mistral** shell utility interacts with OpenStack Mistral API from the
+command-line. It supports the features in the OpenStack Mistral API.
+
+Basic Usage
+-----------
+
+In order to use the CLI, you must provide your OpenStack credentials
+(for both user and project), and auth endpoint. Use the corresponding
+configuration options (``--os-username``, ``--os-password``,
+``--os-project-name``, ``--os-user-domain-id``, ``os-project-domain-id``, and
+``--os-auth-url``), but it is easier to set them in environment variables.
+
+.. code-block:: shell
+
+    $ export OS_AUTH_URL=http://<Keystone_host>:5000/v2.0
+    $ export OS_USERNAME=admin
+    $ export OS_TENANT_NAME=tenant
+    $ export OS_PASSWORD=secret
+    $ export OS_MISTRAL_URL=http://<Mistral host>:8989/v2
+
+When authenticating against keystone over https:
+
+.. code-block:: shell
+
+    $ export OS_CACERT=<path_to_ca_cert>
+
+Once you've configured your authentication parameters, you can run **mistral**
+commands.  All commands take the form of::
+
+    mistral <command> [arguments...]
+
+Run **mistral --help** to get a full list of all possible commands, and run
+**mistral help <command>** to get detailed help for that command.

+Using Mistral without Authentication
+====================================
+
+It is possible to execute a workflow on any arbitrary cloud without additional
+configuration on the Mistral server side. If authentication is turned off in
+the Mistral server (Pecan's `auth_enable = False` option in `mistral.conf`),
+there is no need to set the `keystone_authtoken` section. It is possible to
+have Mistral use an external OpenStack cloud even when it isn't deployed in
+an OpenStack environment (i.e. no Keystone integration).
+
+This setup is particularly useful when Mistral is used in standalone mode,
+where the Mistral service is not part of the OpenStack cloud and runs
+separately.
+
+To enable this operation, the user can use ``--os-target-username``,
+``--os-target-password``, ``--os-target-tenant-id``,
+``--os-target-tenant-name``, ``--os-target-auth-token``,
+``--os-target-auth-url``, ``--os-target_cacert``, and
+``--os-target-region-name`` parameters.
+
+For example, the user can return the heat stack list with this setup as shown
+below:
+
+.. code-block:: shell
+
+    $ mistral \
+        --os-target-auth-url=http://keystone2.example.com:5000/v3 \
+        --os-target-username=testuser \
+        --os-target-tenant=testtenant \
+        --os-target-password="MistralRuleZ" \
+        --os-mistral-url=http://mistral.example.com:8989/v2 \
+        run-action heat.stacks_list
+
+The OS-TARGET-* parameters can be set in environment variables as:
+
+.. code-block:: shell
+
+    $ export OS_TARGET_AUTH_URL=http://keystone2.example.com:5000/v3
+    $ export OS_TARGET_USERNAME=admin
+    $ export OS_TARGET_TENANT_NAME=tenant
+    $ export OS_TARGET_PASSWORD=secret
+    $ export OS_TARGET_REGION_NAME=region
