I was thinking of the former. I have a Getting Started book
because I have other topics that a new user needs to look at. I'd
say that a single getting started topic would suffice for you with
links elsewhere. If I was pedantic I'd remain those other topics to
"xxxxxxxx Overview" though.
Indented keywords are really just to provide a second level
of index. For example you can have a first level of "Creating" and
a second level of "Topics", "Table of Contents", etc.
