+=head1 UPGRADING
+
+Since lei runs as a daemon, L<lei-daemon-kill(1)> is required to kill
+the daemon so it can load new code. It will be restarted with the
+next invocation of any lei command.
+
+=head1 CAVEATS
+
+IMAP and NNTP client performance is poor on high-latency connections.
+It will hopefully be fixed in 2022.
