+    <title>Description</title>
+
+    <para><filename>systemd-suspend.service</filename> is a system
+    service that is pulled in by <filename>suspend.target</filename>
+    and is responsible for the actual system suspend. Similarly,
+    <filename>systemd-hibernate.service</filename> is pulled in by
+    <filename>hibernate.target</filename> to execute the actual
+    hibernation. Finally,
+    <filename>systemd-hybrid-sleep.service</filename> is pulled in by
+    <filename>hybrid-sleep.target</filename> to execute hybrid
+    hibernation with system suspend.</para>
+
+    <para>Immediately before entering system suspend and/or
+    hibernation <filename>systemd-suspend.service</filename> (and the
+    other mentioned units, respectively) will run all executables in
+    <filename>/usr/lib/systemd/system-sleep/</filename> and pass two
+    arguments to them. The first argument will be
+    <literal>pre</literal>, the second either
+    <literal>suspend</literal>, <literal>hibernate</literal>, or
+    <literal>hybrid-sleep</literal> depending on the chosen action.
+    Immediately after leaving system suspend and/or hibernation the
+    same executables are run, but the first argument is now
+    <literal>post</literal>. All executables in this directory are
+    executed in parallel, and execution of the action is not continued
+    until all executables have finished.</para>
+
+    <para>Note that scripts or binaries dropped in
+    <filename>/usr/lib/systemd/system-sleep/</filename> are intended
+    for local use only and should be considered hacks. If applications
+    want to be notified of system suspend/hibernation and resume,
+    there are much nicer interfaces available.</para>
+
+    <para>Note that
+    <filename>systemd-suspend.service</filename>,
+    <filename>systemd-hibernate.service</filename>, and
+    <filename>systemd-hybrid-sleep.service</filename>
+    should never be executed directly. Instead, trigger system sleep
+    states with a command such as <literal>systemctl suspend</literal>
+    or similar.</para>
+
+    <para>Internally, this service will echo a string like
+    <literal>mem</literal> into <filename>/sys/power/state</filename>,
+    to trigger the actual system suspend. What exactly is written
+    where can be configured in the <literal>[Sleep]</literal> section
+    of <filename>/etc/systemd/sleep.conf</filename> or a
+    <filename>sleep.conf.d</filename> file. See
