Info: An Introduction
*********************

   The GNU Project distributes most of its on-line manuals in the "Info
format", which you read using an "Info reader".  You are probably using
an Info reader to read this now.

   If you are new to the Info reader and want to learn how to use it,
type the command `h' now.  It brings you to a programmed instruction
sequence.

   To read about expert-level Info commands, type `n' twice.  This
brings you to `Info for Experts', skipping over the `Getting Started'
chapter.
