Hi!
"Zen is a powerful, yet simple, HTML5 starting theme with a responsive,
mobile-first grid design. If you are building your own standards-compliant
theme, you will find it much easier to start with Zen than to start with
Garland or Stark. This theme has fantastic online documentation and tons of
helpful code comments in its PHP, HTML, CSS and Sass."
I've created that theme for Fedora/EPEL, you can review it here.[1]
