While man is the most ubiquitous documentation format, info
is much more powerful. It provides hypertext links to make reading
large documents much easier and many features for the documentation
writer. There are some very complete info documents
on various aspects of Red Hat (especially the portions from the GNU project).
To read info documentation, use the info program without
any arguments. It will present you with a list of available documentation. If
it can't find something, it's probably because you don't have the package
installed that includes that documentation. Install it with RPM and
try again.
If you're comfortable using emacs, it has a built in browser for info
documentation. Use C-h C-i to see it.
The info system is a hypertext based system. Any highlighted
text that appears is a link leading to more information. Use the Tab
key to move the cursor to the link, and press Enter to follow the
link. Pressing p returns you to the previous page, n moves you
to the next page, and u goes up one level of documentation. To
exit info, press C-x C-c (that's control-x followed by control-c).
The best way to learn how to use info is to read the info documentation
on it. If you read the first screen that info presents you'll be
able to get started.
