For optimum presentation in the gallery, notebooks should follow a few simple rules:
The first cell must be a Markdown cell containing a title
The first cell should include a short summary, which will be shown as a tooltip
By default, the chosen thumbnail is the last matplotlib figure in the
notebook. This can be changed by setting the
in the notebook metadata to the integer index of the desired
figure. This can be done manually, in a text editor, or through the
Edit -> Edit Notebook Metadata menu in jupyter.
If including external images (i.e. not plots generated in the code) in
notebooks, place them in the
images/ directory next to the
notebook. Use the syntax
![image caption](images/image.png) to
include the image in the notebook, and add
(replaced by the correct path) into the
list in the notebook metadata.
