+Gallery
+=======
+
+The gallery is divided into sections as described below.  All entries
+show the code used to produce the example plot.  Additionally there are links
+to download the code directly as source or as part of a 
+`jupyter notebook <https://jupyterlab.readthedocs.io/en/stable/>`_, 
+these links are at the bottom of the page.
+
+In order to successfuly view the jupyter notebook locally so you may
+experiment with the code you will need an environment setup with the 
+appropriate dependencies, see :ref:`installing_iris` for instructions.  
+Ensure that ``iris-sample-data`` is installed as it is used in the gallery.  
+Additionally ensure that you install ``jupyter``.  The command to install both
+is::
+
+    conda install -c conda-forge iris-sample-data jupyter
+
+Once you have downloaded the notebooks (bottom of each gallery page), 
+you may start the jupyter notebook via::

+  jupyter notebook
