Chapter 14 could use a little bit more information on exactly
what the selectable repositories are.

A first time user might not understand why there are three
repositories listed.  Even a little bit of information here
might help him or her to understand why each one should (or
should not be) selected.

"Installation Repo" - your install media
"Fedora 10 - i386" - (I'm not quite sure what this is)
"Fedora 10 - i386 -  Updates" - I think this is packages
   that were updated after the initial release.

I'd like to suggest some text here but I'm not familiar enough
with what these are to give a really precise explanation.
