+@file{~/.bash_profile} or @file{~/.zprofile} will be used to set up
+environment variables for the user instead of @file{/etc/profile}.  And
+search-paths from multiple profiles are honored, which means a system
+configured Xfce desktop environment can find its panel plugins in the user
+profile.
+
+Before run @command{guix system reconfigure}, append the snippet below to each
+user's @file{~/.bash_profile} or @file{~/.zprofile}:
+
+@example
+# Merge search-paths from multiple profiles, the order matters.
+eval \"$(guix package --search-paths \\
+-p $HOME/.config/guix/current \\
+-p $HOME/.guix-profile \\
+-p /run/current-system/profile)\"
+
+# Prepend setuid programs.
+export PATH=/run/setuid-programs:$PATH
+
+# Set up Guix Home profile
+if [ -d ~/.guix-home ]; then . ~/.profile; fi
+@end example
+
+Or you can override them with updated skeleton files after system reconfigure.
+In addition, Guix Home users need to upgrade via @command{guix home
+reconfigure}.  See @uref{https://issues.guix.gnu.org/20255} for the
+rationale.")))
