5) Service activation (Pacemaker)
+It is also possible to use Mistral actions or workflows together with
+a deployment step, these are executed before the main configuration run.
+To describe actions or workflows from within a service use:
+
+ * service_workflow_tasks: One or more workflow task properties
+
+which expects a map where the key is the step and the value a list of
+dictionaries descrbing each a workflow task, for example::
+
+ service_workflow_tasks:
+ step2:
+ - name: echo
+ action: std.echo output=Hello
+ step3:
+ - name: external
+ workflow: my-pre-existing-workflow-name
+ input:
+ workflow_param1: value
+ workflow_param2: value
+
+The Heat guide for the `OS::Mistral::Workflow task property
+<https://docs.openstack.org/developer/heat/template_guide/openstack.html#OS::Mistral::Workflow-prop-tasks>`_
+has more details about the expected dictionary.
