rbCMS is running, at
runbasicnet.com/demo/ Source code is at
runbasicnet.com/demo/rbcms_project.zip Read through the (incomplete!) demo stuff, play with the (complete!) personality test, download the code, set up a project in your RB root. NOTE: rbCMS looks for index.cms as its default start file. So create one of those, first.
The switch between viewer and editor modes is explained in the source. It's an Easter-egg thing, to keep it out of the way.
The Help file is a rough cut, and incomplete!!! But I'll keep plugging away at it. And the Tutorial has not been started at all. But you should be able to figure out how to get started from the demo materials and the source code. I've got way too much non-programming stuff to do, to keep this under wraps until it's done and perfect. Treat it like the pre-Alpha it is, and let me know what else you need.
