+@chapter GNU Distribution
+
+Guix comes with a distribution of free software@footnote{The term
+``free'' here refers to the
+@url{http://www.gnu.org/philosophy/free-sw.html,freedom provided to
+users of that software}.} that form the basis of the GNU system. This
+includes core GNU packages such as GNU libc, GCC, and Binutils, as well
+as many GNU and non-GNU applications. The complete list of available
+packages can be seen by running @command{guix-package} (@pxref{Invoking
+guix-package}):
+
+@example
+guix-package --list-available
+@end example
+
+The package definitions of the distribution may are provided by Guile
+modules in the @code{(gnu packages ...)} name space---for instance, the
+@code{(gnu packages emacs)} module exports a variable named
+@code{emacs}, which is bound to a @code{<package>} object
+(@pxref{Defining Packages}). The @code{(gnu packages)} module provides
+facilities for searching for packages.
+
+The distribution is fully @dfn{bootstrapped} and @dfn{self-contained}:
+each package is built based solely on other packages in the
+distribution. The root of this dependency graph is a small set of
+@dfn{bootstrap binaries}, provided by the @code{(gnu packages
+bootstrap)} module. These are statically-linked binaries of the core
+tools without which building anything at all would be impossible.
+
+
+Our goal is to build a practical 100% free software distribution of
+Linux-based and other variants of GNU, with a focus on the promotion and
+tight integration of GNU components, and an emphasis on programs and
+tools that help users exert that freedom.
+
+Building this distribution is a cooperative effort, and you are invited
+to join! Please get in touch with us on @email{bug-guix@@gnu.org}. We
+welcome ideas, bug reports, patches, and anything that may be helpful to
+the project.
