Welcome to PC-BSD and many thanks for your interest.
Early in 2005, Kris Moore, the founder of PC-BSD, presented the first beta version of PC-BSD, an easy-to-use
FreeBSD-based operating system pre-configured for desktop use. Since then, PC-BSD has matured into a
polished, feature-rich, free-of-charge, open source operating system that anyone can use, from the beginner to
the advanced user alike.
PC-BSD is essentially a customized installation of FreeBSD, not a forked derivative. Since the underlying
FreeBSD system has been kept intact, you have a fully functional FreeBSD system under the hood. PC-BSD is
basically a pre-configured FreeBSD with a graphical installer, graphical package management, pre-installed
packages, and some handy graphical utilities to make PC-BSD suitable for desktop use. As a user of PC-BSD,
you don’t have to worry about configuring your system; instead you can simply install and start using it.
