The MBSEQv4 beginner's guide is now up on the wiki with some images. I've used EsotericLabs' eps files (based on Wilba's design) for frontpanel overview images, I hope it's ok.
In principle the guide is exportable as pdf and printable (there's a button on the right), though at the moment certain "table like things" don't get rendered correctly. I might replace the "tables" with images to take care of the problem.
If you want to add sections and correct stuff, go ahead, that's the wiki way :-)
