+6. Specifying ordering
+
+Specify default ordering for a model using the ``ordering`` attribute, which
+should be a list or tuple of field names. This tells Django how to order
+``QuerySet`` results.
+
+If a field name in ``ordering`` starts with a hyphen, that field will be
+ordered in descending order. Otherwise, it'll be ordered in ascending order.
+The special-case field name ``"?"`` specifies random order.
+
+The ordering attribute is not required. If you leave it off, ordering will be
+undefined -- not random, just undefined.
