It's not just poorly documented - it's not documented at all. No matter how I tried, I couldn't get the theme to link to blog posts while keeping the default static front page (the way it's seen on the developers' demo). Looks like that's asking too much from this "Lite" version. No custom menu support, which is a nonsense for a modern theme. Latest posts on the front page don't work, despite there being a setting for that on the Theme Options. Footer feature also doesn't work out of Theme Options, although it can be set via widgets.
All in all, the theme is generally unusable, although the demo might look deceivingly pretty. I'd strongly advise against installing it.
