CentOS is an Enterprise-class Linux Distribution derived from sources freely providedto the public by Red Hat, Inc. for Red Hat Enterprise Linux. CentOS conforms fully with the upstream vendorsredistribution policy and aims to be functionally compatible. (CentOS mainly changes packages to remove upstream vendorbranding and artwork.)
CentOS is developed by a small but growing team of coredevelopers. In turn the core developers are supported by an active user communityincluding system administrators, network administrators, enterprise users, managers, core Linux contributors and Linux enthusiasts from around the world.
CentOS has numerous advantages including: an active and growing user community, quickly rebuilt, tested, and QA'ed errata packages, an extensive mirror network, developers who are contactable and responsive, Special Interest Groups (SIGs) to add functionality to the core CentOS distribution, and multiple community support avenues including a wiki, IRC Chat, Email Lists, Forums, Bugs Database, and an FAQ.
