Nice to see you chime in While I have the ear of one of the founders of a CMS I'll throw my 2 cents in.
I love, love, love what the founders at Couch have done. Taken a REAL WORLD example site, complete with a homepage, blog/news section, portfolio section, etc & did a complete walk-through (while explaining the system along the way) of how to take a plain CSS/HTML build & turn it into a functioning content managed website.
Granted, the tutorial & site they have used looks a bit dated, but I feel like after reading through I have a very solid grasp on how to port a basic brochure type of site with a blog/news section (and even pull some of the data from the blog section back into the homepage.)
I'm new to development in general, so reading through documentation about "templates", "tags", "PHP includes", etc alone can seem rather daunting & a little tough to wrap my head around. Couch is no different, they have a dedicated section that contains all the usual dry & vague CMS lingo noted above. The only difference is their walk-through actually made me understand how to put it all to use.
I noticed you guys seem to offer a bit more in terms of documentation & guidance than the majority of content management systems but you may think about doing a complete walk-through similar to how the folks at Couch have done.
