Well, as a dedicated VSD user here is my opinion...
I am an avid reader and agree with Jo Ann that 'detailed' documentation would be an asset.
That said, as far as a 'quick start' guide, here is what I would like to see...
I think a simple 'walk through' from start to finish of a simple 1 or 2 page site would be great. Maybe a video. Show adding full page background images as well as other page images, how to include items such as sliders, videos, music, menus, forms and such. and of course, how to export and/or publish the site to both S-Drive or your own server. A picture is worth a thousand words. Videos are even better!
Quick Start Guide:
1)
An easy to understand explanation of the 'Grid', 'Row', 'Column' layout.
I have played around with RLM but since I don't really code I never really 'got it'. I have started a site with RSD ( yes, I really have ) but my time is limited and I just haven't gone to far. I understand the layout, mostly, but it took a while to figure out just how to add a background image that covered the whole page. ( a repeating image ) May seem simple to some coders but not so much to the rest of us.
2)
Explain ( again ) about the desktop down or mobile up design theory.
I still think a lot of users don't understand that.
3)
Explain where 'Resources' are and how they are used.
I figured that one out, and love how you did it. I'm just thinking of 'newbies' and what they may want/need to know.
4)
Explain how to add a 'Menu Builder' menu
5)
Explain how to add a WFB form
6)
Explain how to save, export and publish a site
7)
Explain how to load and modify a theme
I know this may seem simple and a lot more information may be in a quick start guide, but these basics should get a 'new' user started. I just think some theory/explanation of the whole responsive design concept should be included at the beginning of the guide. Nothing to deep, just give an understanding of how the responsive system differs from the 'old' web design types and why users should go responsive. Then just give the basics.
My opinion.
