+@subsection Guix Home Services
+
+The @code{(gnu home services guix)} module provides services for
+user-specific Guix configuration.
+
+@defvr {Scheme Variable} home-channels-service-type
+This is the service type for managing
+@file{$XDG_CONFIG_HOME/guix/channels.scm}, the file that controls the
+channels received on @command{guix pull} (@pxref{Channels}). Its
+associated value is a list of @code{channel} records, defined in the
+@code{(guix channels)} module.
+
+Generally, it is better to extend this service than to directly
+configure it, as its default value is the default guix channel(s)
+defined by @code{%default-channels}. If you configure this service
+directly, be sure to include a guix channel. @xref{Specifying
+Additional Channels} and @ref{Using a Custom Guix Channel} for more
+details.
+
+A typical extension for adding a channel might look like this:
+
+@lisp
+(simple-service 'variant-packages-service
+ home-channels-service-type
+ (list
+ (channel
+ (name 'variant-packages)
+ (url "https://example.org/variant-packages.git")))
