This chapter gave you just a brief introduction to GNOME. Fortunately, GNOME comes with extensive user documentation, including a short GNOME Desktop manual. As previously stated, you can access general help by clicking on your panel's life buoy, or by right-clicking on the panel and choosing Help.
The GNOME Help Browser allows you to read documentation for non-GNOME applications, such as man pages and info pages. The standard documentation format for command-line applications comes in the form of man pages. They are usually very detailed but rather technical. Info pages are the documentation format used by utilities from the GNU project, such as (arguably) the most powerful text editor ever created, Emacs.
Finally, if your computer is connected to the Internet, you can also find a wealth of information about GNOME on the web. Point your web browser to the GNOME web site and explore!
