 @cindex configuration of @command{guix pull}
 Guix and its package collection are updated by running @command{guix pull}
 (@pxref{Invoking guix pull}).  By default @command{guix pull} downloads and
-deploys Guix itself from the official GNU@tie{}Guix repository.  This can be
-customized by defining @dfn{channels} in the
-@file{~/.config/guix/channels.scm} file.  A channel specifies a URL and branch
-of a Git repository to be deployed, and @command{guix pull} can be instructed
-to pull from one or more channels.  In other words, channels can be used
-to @emph{customize} and to @emph{extend} Guix, as we will see below.
-Guix is able to take into account security concerns and deal with authenticated
-updates.
