+2. Adding __str__() or __unicode__() to models
+
+Although it's not a strict requirement, each model should have a
+``_str__()`` or ``__unicode__()`` method to return a "human-readable"
+representation of the object. Do this not only for your own sanity when dealing
+with the interactive prompt, but also because objects' representations are used
+throughout Django's automatically-generated admin.
+
+Normally,  you should write ``__unicode__()`` method, since this will work for
+all field types (and Django will automatically provide an appropriate
+``__str__()`` method). However, you can write a ``__str__()`` method directly,
+if you prefer. You must be careful to encode the results correctly, though.
