5.What does the reader need?

To get any real benefit from the guide, the reader must have access (whether physical access or via SSH) [2] to a computer running Linux. Similarly, for the reader to benefit from sections in the guide that cover specific programs (such as Section5.2, “GNU Emacs”), the software under discussion must be installed.

[2] Wikipedia's article on SSH describes it as "a network protocol that allows data to be exchanged using a secure channel between two networked devices." A discussion of SSH is beyond the scope of the guide, but the Wikipedia article may be helpful in learning more. If you're a student, you can try asking at the help desk at your school's computing center.
