+                    Lists the layers, separated by spaces, recommended for
+                    use with this layer.
+                    Optionally, you can specify a specific layer version for a
+                    recommendation by adding the version to the end of the
+                    layer name.
+                    Here is an example:
+                    <literallayout class='monospaced'>
+     LAYERRECOMMENDS_mylayer = "anotherlayer (=3)"
+                    </literallayout>
+                    In this previous example, version 3 of "anotherlayer" is
+                    compared against
+                    <filename>LAYERVERSION_anotherlayer</filename>.
+                </para>
+
+                <para>
+                    An error is produced if any dependency is missing or the
+                    version numbers (if specified) do not match exactly.
+                    This variable is used in the
+                    <filename>conf/layer.conf</filename> file and must be
+                    suffixed with the name of the specific layer (e.g.
+                    <filename>LAYERRECOMMENDS_mylayer</filename>).
+                </para>
