The man command (short for "manual") is great for listing documentation associated with a particular Linux command, but there is lesser-known, and arguably superior alternative, called info.

info works in a multipage, hypertext format for which you'll need a few basic navigation commands:

n - Next page p - Previous page u - Upper page l - Last page visited d - Go to info's main directory x - Exit the current window (if a sub-window is open) q - Quit

Links are prefixed with a "*". To follow a link, move the cursor over the text that follows it and press <Enter>.

The best way to get started is to simply type info on its own. From there, typing h will give you a primer for first timers, while q will list the basic commands.
