+21. Specifying 'choices' for a field
+
+Most fields take a ``choices`` parameter, which should be a tuple of tuples
+specifying which are the valid values for that field.
+
+For each field that has ``choices``, a model instance gets a
+``get_fieldname_display()`` method, where ``fieldname`` is the name of the
+field. This method returns the "human-readable" value of the field.
