Thanks for the comments - spaceBase engineer here. We're currently working on building out the documentation and solid demo. We laid out some of the basics to get people up and running and work with the architecture. More to come soon though. Feel free to dig in further and send along feedback.

Hmmm another grid that uses floats also can't seem to find any documentation for it?

Would suggest using something like https://github.com/csswizardry/csswizardry-grids instead.

Is there documentation that I am missing?

really nice, well done and great job working with parsons on his!
