Idea: asciinema for the CLI tutorial

[cschwan]

The CLI tutorial happens - unsurprisingly - mainly in the shell, so it would be an interesting idea to use https://asciinema.org/ to show it running in a video container.

Concerning the "video container", GitHub's Markdown renderer supports videos, and even GIFs :)

E.g. https://github.com/alelievr/Mixture/ (it was the one cited by SO, and has both, but I have seen them in many other projects).
