+Adding a notebook
+-----------------
+
+You can add a notebook here to be included in the docs by creating a symlink to an existing notebook.
+This lets you keep them in the original place,
+but also include them in your docs here.
+
+This would be done with a command like this::
+
+    ln -s ../../Examples/Gentle-Intro-To-HARK.ipynb .
+
+That would create a symlink here to the ``Examples/Gentle-Intro-To-HARK.ipynb`` notebook.
