There are many ways to get GNOME on your system. This section covers the most common questions involved in the process.
Currently, you need a machine with Unix or a Unix-like operating system installed, with the X Window System (X11R5 or later). You need at least 16MB of RAM, although I expect you'll be happier with 32MB or more. If you are just installing binaries, you need about 30MB of disk space, count on needing at least 200MB of disk space if you are compiling from source.
