+  **Maintainer (team lead)**:
+  - Create an exercise repository by
+    [generating from a template](https://help.github.com/en/articles/creating-a-repository-from-a-template)
+    using this template: <https://github.com/coderefinery/template-forking-workflow-exercise>
+    called `forking-workflow-exercise`
+  - In this case we **do not add collaborators** to the repository (this is the point of this example).
+  - Share the link to the newly created repository with your group.
+
+  **Learners in exercise team**: Fork the newly created repository (not the
+  "coderefinery" one) and then **clone your fork** (if you wish to work locally).
