+    initiates the resume from hibernation. It is instantiated with the
+    device to resume from as the template argument.</para>
+
+    <para><filename>systemd-hibernate-resume</filename> only supports
+    the in-kernel hibernation implementation, known as
+    <ulink url="https://www.kernel.org/doc/Documentation/power/swsusp.txt">swsusp</ulink>.
+    Internally, it works by writing the major:minor of specified
+    device node to <filename>/sys/power/resume</filename>.</para>
+
+    <para>Failing to initiate a resume is not an error condition. It
+    may mean that there was no resume image (e. g. if the system has
+    been simply powered off and not hibernated). In such case, the
+    boot is ordinarily continued.</para>
