What part of the 300+ pages? There is such thing as too detailed for a manual, in particular when it lacks a "quick dive-in" section that provides an shallow but wide overview of all the main features.
As I said, I followed several of the shapes and paths tutorials. That still didn't make the tool intuitive. I've just found this [1] "crash course" that might have just the right level of detail; it would be great if something like that was linked from Inkscape's help menu with a neon-flashing "start here!" button.
I'd have thought he meant the Help menu pages, that are themselves Inkscape files, that run through all the basics. I've found them well made and very useful. Eg Help > Tutorials > Basic.
