HUGO

Cant build my site with zzo theme

hello guys, i have been trying to build my website using the zzo theme from the official repository. I followed the guide on the zzo page: https://zzodocs.netlify.com/docs/gettingstarted/quickstart/
when launching hugo server, everything works as expected but when i just run hugo and build the website and click public/index.html there is no theme displayed.just a page saying Example domain.
