+Load the [Python Workflow Definition](https://pythonworkflow.github.io) with the visual programming environment [pyironflow](https://github.com/pyiron/pyironflow):
 
 ```python
 from pyironflow import PyironFlow
 from python_workflow_definition.pyiron_workflow import load_workflow_json
 
 PyironFlow([load_workflow_json(file_name="workflow.json")]).gui
 ```
+
+The main motivation for supporting visual programming environments with the Python Workflow Definition is that they simplify the discussion of workflows. 
+When we introduce a new workflow, we commonly illustrate it as data flow diagram. A visual programming environment allows you to:
+
+- Browse through the workflow and zoom in on individual parts to analyze which data is transferred between the different steps.
+- Furthermore, a visual programming environment enables debugging the data flow, by allowing the user to execute individual steps, or the workflow up to a specific step and print the data at a given step.
+- Finally, for technically less inclined users a visual programming environment provides the ability to use workflow developed by experts. This accelerates the knowledge transfer between different user groups.
+
+In conclusion the visual programming approach provides an alternative perspective to working with the Python Workflow Definition.
