+@subsubsection Command-line interface
+
+Mumi also comes with a command-line interface that can be used to search
+existing issues, open new issues and send patches.  You do not need to
+use Emacs to use the mumi command-line client.  You interact with it
+only on the command-line.
+
+To use the mumi command-line interface, navigate to a local clone of the
+guix git repository, and drop into a shell with mumi, git and
+git:send-email installed.
+
+@example
+$ cd guix
+~/guix$ guix shell mumi git git:send-email
+@end example
+
+To search for issues, say all open issues about "zig", run
+
+@example
+~/guix [env]$ mumi search zig is:open

+@end example
+
+Pick an issue and make it the "current" issue.
+
+@example
+~/guix [env]$ mumi current 61036
+
+#61036 [PATCH 0/3] Update zig to 0.10.1

+@end example
+
+Once an issue is the current issue, you can easily create and send
+patches to it using
+
+@example
+~/guix [env]$ git format-patch origin/master
+~/guix [env]$ mumi send-email foo.patch bar.patch
+@end example
+
+Note that you do not have to pass in @samp{--to} or @samp{--cc}
+arguments to @command{git format-patch}.  @command{mumi send-email} will
+put them in correctly when sending the patches.
+
+To open a new issue, run
+
+@example
+~/guix [env]$ mumi new
+@end example
+
+and send patches
+
+@example
+~/guix [env]$ mumi send-email foo.patch bar.patch
+@end example
+
+@command{mumi send-email} is really a wrapper around @command{git
+send-email} that automates away all the nitty-gritty of sending patches.
+It uses the current issue state to automatically figure out the correct
+@samp{To} address to send to, other participants to @samp{Cc}, headers
+to add, etc.
+
+Also note that, unlike @command{git send-email}, @command{mumi
+send-email} works perfectly well with single and multiple patches alike.
+It automates away the debbugs dance of sending the first patch, waiting
+for a response from debbugs and sending the remaining patches.  It does
+so by sending the first patch, polling the server for a response, and
+then sending the remaining patches.  This polling can unfortunately take
+a few minutes.  So, please be patient.
+
+@subsubsection Emacs interface
+
 If you use Emacs, you may find it more convenient to interact with
 issues using @file{debbugs.el}, which you can install with:
