Minimum distributables to get typeahead.js working

I’m trying to get started with typeahead.js.

I’m trying some of the examples on the examples page, but nothing is working. The menu wouldn’t come up. And when I finally did get the menu to display, it has a transparent background.

Does anyone know where the minimal steps are documented to get this component working? Do I need some CSS files? Which js files are needed?

Again, I don’t want Bloodhound or anything else beyond the absolute minimum Which files do I need?
