How To Design in UNA 11?

After scouring the internet for days, and this community, and the Github community, I have found only 1 video of how to actually use this program, and it was v. 10.  I have also found no information whatsoever on this subject on this site, or forums, or discussions, etc, or at least, none step-by-step or extensive enough to be used in any way that is thorough enough to create something tangible, full, and extensive.  Does anyone have any links, videos, anything?  I have a very unique idea and I have a back-end coder awaiting my instructions to tweak the program, but I can't hire her to do so if there is no conceivable way to design my site.  Thank you!
