FreeBSD Handbook

The FreeBSD Documentation Project

Welcome to FreeBSD! This handbook covers the installation and day to day use of FreeBSD 4.10-RELEASE and FreeBSD 5.2.1-RELEASE. This manual is a work in progress and is the work of many individuals. Many sections do not yet exist and some of those that do exist need to be updated. If you are interested in helping with this project, send email to the FreeBSD documentation project mailing list. The latest version of this document is always available from the FreeBSD web site. It may also be downloaded in a variety of formats and compression options from the FreeBSD FTP server or one of the numerous mirror sites. If you would prefer to have a hard copy of the handbook, you can purchase one at the FreeBSD Mall. You may also want to search the handbook.
