I'll add this. I have another one in this category to add:

What chapter do you think these will go in?

That's a good question. They are both extensions, so maybe in a section on how to extend. But also both are engagement/teaching practices, so, maybe in Tips and Tricks in Chapter 5...

[willingc]

I only ask because I've been trying to indicate the "where" in the issue titles which will be useful for future contributors.

[labarba]

This should go in Ch.5: Jupyter Notebook ecosystem.

Note that I've pushed two images to include with the description of nbtutor, but I've not added the text. https://github.com/jupyter4edu/jupyter-edu-book/tree/master/images

@labarba do you want to add the nbtutor text? I've already added the section I mentioned above.

[labarba]

I was planning to, but have been swamped this week (last week of classes, many meetings, lots of admin).

No rush! I'll leave this for you, as I use (and wrote) a different one: http://nbviewer.jupyter.org/github/Calysto/metakernel/blob/master/examples/Tutor%20Magic%20in%20IPython.ipynb
