into the file.

+
+Mistral is a workflow service. Most business processes consist of multiple
+distinct interconnected steps that need to be executed in a particular
+order in a distributed environment. A user can describe such a process as a set
+of tasks and their transitions. After that, it is possible to upload such a
+description to Mistral, which will take care of state management, correct
+execution order, parallelism, synchronization and high availability.
+
+Mistral also provides flexible task scheduling so that it can run a process
+according to a specified schedule (for example, every Sunday at 4.00pm) instead
+of running it immediately. In Mistral terminology such a set of tasks and
+relations between them is called a workflow.

-    | git clone git://git.openstack.org/openstack/python-mistralclient.git
-    | cd python-mistralclient
+    $ git clone git://git.openstack.org/openstack/python-mistralclient.git
+    $ cd python-mistralclient
 
 Then just run:
 
-    pip install -e .

+    $ export OS_MISTRAL_URL=http://<Mistral host>:8989/v2  (optional, by
       default URL=http://localhost:8989/v2)
 
 and in the case that you are authenticating against keystone over https:
 
-    export OS_CACERT=<path_to_ca_cert>
+    $ export OS_CACERT=<path_to_ca_cert>
