+                    It is an important distinction that
+                    <filename>COREBASE</filename> points to the parent of this
+                    layer and not the layer itself.
+                    Consider an example where you have cloned the Poky Git
+                    repository and retained the <filename>poky</filename>
+                    name for your local copy of the repository.
+                    In this case, <filename>COREBASE</filename> points to
+                    the <filename>poky</filename> folder because it is the
+                    parent directory of the <filename>poky/meta</filename>
+                    layer.
