+ImageShow.IPythonViewer
+^^^^^^^^^^^^^^^^^^^^^^^
 
-TODO
+If IPython is present, this new ``ImageShow.Viewer`` subclass will be
+registered. It displays images on all IPython frontends. This will be helpful
+to users of Google Colab, allowing ``im.show()`` to display images.
+
+It is lower in priority than the other default Viewer instances, so it will
+only be used by ``im.show()`` or ``ImageShow.show()`` if none of the other
+viewers are available. This means that the behaviour of ``ImageShow`` will stay
+the same for most Pillow users.
