The LTT video pretty much covered it all, actually. There's really no tinkering. It's a straightforward wizard kind of thing. Probably more useful to get some guides on the post-setup dashboard/UI, in my opinion.
That said, there IS a visual guide you can view once you have gotten access to the expanded Forums (which you get once you get your invite). This only covers the actual install process, none of the post-installation configs.
