An asciinema.org screencast?

Perhaps it would be a good idea to add a screencast to the homepage like the one visible on https://asciinema.org/ ?

Start at the website homepage and review the screencast example linked from asciinema.org. Determine how the homepage should present the screencast; done means a working screencast is visible there and matches the intended presentation.
