+# === Welcome to the template Renku Workflow file! ===
+# You can use this file to encode in what order your data processing steps should be run,
+# making it easier for you to run your workflow, and for others to understand it!
+
+# === How to use this template ===
+# Replace the script and data paths in the template below to match your analysis commands. 
+# Then, run `renku run my-workflow.yaml` in a terminal to execute the workflow!
+# If you are working in a notebook, run `! renku run my-workflow.yaml` in a notebook cell.
