Many computer users have an insatiable appetite to deepen their understanding of computer operating systems and computer software. Linux users are no different in that respect. At the same time as developing a huge range of open source software, the Linux community fortunately has also written a vast range of documentation in the form of books, guides, tutorials, HOWTOs, man pages, and other help to aid the learning process. Some of this documentation is intended specifically for a newcomer to Linux, or those that are seeking to move away from a proprietary world and embrace freedom.
