+## Publish your workflow
+You can publish your workflow in five simple steps:
+* Fork the repository and clone your fork locally.
+* Export your workflow to the Python Workflow Definition using the `python_workflow_definition` Python package, by calling the `write_workflow_json()` function.  
+* Replace the `environment.yml`, `workflow.py` and `workflow.json` in your local folder with the files for your workflow. In addition, you can add additional files if they are required and update the `README.md` to explain your workflow.
+* Commit the files locally using `git add -A` and `git commit -m "add my workflow"`
+* Push your workflow to Github `git push`
