+Git repository by verifying commit signatures and ensuring they all come from
+authorized parties, exactly like @command{guix pull} now does.
+
+This command is primarily useful to developers of channels.  It allows them to
+ensure, before pushing, that the channel only contains commits signed with
+authorized keys.  But this command is also useful anytime you use Git and want
+to allow people to authenticate code fetched from your repository.
+
+Run @command{info \"(guix) Invoking guix git authenticate\"} for more info,
+and see @uref{https://guix.gnu.org/blog/2020/securing-updates/} for details on
+these mechanisms.")))
