+
+    <para><command>systemd-journal-gatewayd</command> serves journal

+    HTTPS connections.</para>
+
+    <para>The program is started by
+    <citerefentry><refentrytitle>systemd</refentrytitle><manvolnum>1</manvolnum></citerefentry>
+    and expects to receive a single socket. Use

+    the service, and <command>systemctl enable systemd-journal-gatewayd.socket</command>
+    to have it started on boot.</para>
