+Good synergy with job module required... job runs every x and might invoke a workflow/workflow-step
+
+## Type
+
+* 1 = Autorun after previous event
+* 2 = Only if event listener is called
+
+Every step receives the status code of all steps + the custom data created from the previous steps
+
+After every step the handler writes custom data to the workflow run information.
+
+This means every workflow has a configuration and whenever a new workflow get's triggered a new "workflow entry" is created.
+
+## Template
+
+e.g. user interface for this step
