The introduction you wrote can mention the main points briefly, and
then have a cross-reference to where the commands are described in
full.  That way, both those who don't know "how to exit vim" will find
what they need (and can follow the cross-reference to read the rest),
and those who read the relevant chapter will have this information
spelled out.
