I'm trying to use this theme while following the official Quick Start guide. Is there any additional configuration needed for this theme to work?

Hugo version: 0.78

Same here. Not working with Hugo v.0.80.0

I came with the same problem, then I realized that there is a doc on how to use this theme. The doc is well written, and it solves this problem.

Make sure you add the config files.
