+    <title>Description</title>
+
+    <para>A unit configuration file whose name ends in
+    <literal>.slice</literal> encodes information about a slice
+    created by systemd to manage resources used by a certain group of
+    processes. This management is performed by creating a node in the
+    control group tree. Those processes are part of different units,
+    usually <literal>.service</literal> units (see
+    <citerefentry><refentrytitle>systemd.unit</refentrytitle><manvolnum>5</manvolnum></citerefentry>).
+    </para>
+
+    <para>See
+    <citerefentry><refentrytitle>systemd.unit</refentrytitle><manvolnum>5</manvolnum></citerefentry>
+    for the common options of all unit configuration
+    files. The common configuration items are configured
+    in the generic [Unit] and [Install] sections. The
+    slice specific configuration options are configured in
+    the [Slice] section. Currently, only generic cgroup settings
+    as described in
+    <citerefentry><refentrytitle>systemd.cgroup</refentrytitle><manvolnum>7</manvolnum></citerefentry> are allowed.
+    </para>
+
+    <para>Unless <varname>DefaultDependencies=false</varname>
+    is used, slice units will implicitly have dependencies of
+    type <varname>Conflicts=</varname> and
+    <varname>Before=</varname> on
+    <filename>shutdown.target</filename>. These ensure
+    that slice units are removed prior to system
+    shutdown. Only slice units involved with early boot or
+    late system shutdown should disable this option.
