To turn your iPython notebook into a slideshow on your local machine type the following at a terminal:

jupyter nbconvert your_notebook.ipynb --to slides --post serve

And if you want to create a portable html file that you can host somewhere like github type the following instead:

jupyter nbconvert your_notebook.ipynb --to slides --reveal-prefix "http://cdn.jsdelivr.net/reveal.js/2.6.2"
