 A wrapper around Amazon's Simple Workflow Service meant to simplify declaring and using activities and workflow. Provides some sane defaults
 and work around some idiosyncracies of the platform.

 You can also define similar hooks for events using the following methods:
 
 * ```on_activity_completed``` is called when an activity completes and SWF reports back to the decision loop.
 * ```on_activity_failed``` is called when an activity reports a failure to SWF.
+
+### Triggering Workflows
+
+You can trigger the worklow with the following command:
+
+```ruby
+SimplerWorkflow::Domain["my-test-domain"].start_workflow("hello-world", "1.0.1", "AWS")
+```
+
+The parameters are the name of the workflow, the version as well as a string representing the input to the workflow.
 
 ## Workflow and Activity Versioning
 
 All workflow types and activity types are versioned under SWF. This allows an organization to release new versions of a workflow or activity
 as they are updated and allow workflows to complete under the old version number if need be.
