If I may be so bold as to comment on form rather than function, I wanted to say I am not particularly fond of the typography / design choices for the tutorial.

I know this is dangerously close to bikeshedding territory, but if I may, I wanted to point you to a similar resource that I recall being particularly pleasing to read way back when I was getting started in Python / Django:

https://web.archive.org/web/20080730140551/http://www.django...

That content has been retired from djangobook.com, and the website's design has followed suit, hence the archive.org link. I suggest also perusing the table of contents and making note of small design hints such as the use of color, whitespace, "Note" callouts, etc.

At the very least, I hope you'll find this inspirational if you decide to take a moment to rethink typography, typesetting and the overall design of the website and PDF.
