+    <literal>.slice</literal> encodes information about a slice which
+    is a concept for hierarchially managing resources of a 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>).
+    control group tree. Units that manage processes (primarilly scope
+    and service units) may be assigned to a specific slice. For each
+    slice, certain resource limits may the be set that apply to all
+    processes of all units contained in that slice. Slices are
+    organized hierarchially in a tree. The name of the slice encodes
+    the location in the tree. The name consists of a dash-separated
+    series of names, which describes the path to the slice from the
+    root slice. The root slice is named,
+    <filename>-.slice</filename>. Example:
+    <filename>foo-bar.slice</filename> is a slice that is located
+    within <filename>foo.slice</filename>, which in turn is located in
+    the root slice <filename>-.slice</filename>.
