    single: External Data Representation
 
 The data format used by :mod:`pickle` is Python-specific.  This has the
 advantage that there are no restrictions imposed by external standards such as
-XDR (which can't represent pointer sharing); however it means that non-Python
-programs may not be able to reconstruct pickled Python objects.

 Module Interface
 ----------------
 
-To serialize an object hierarchy, you first create a pickler, then you call the
-pickler's :meth:`dump` method.  To de-serialize a data stream, you first create
-an unpickler, then you call the unpickler's :meth:`load` method.  The
-:mod:`pickle` module provides the following constant:
+To serialize an object hierarchy, you simply call the :func:`dumps` function.
+Similarly, to de-serialize a data stream, you call the :func:`loads` function.
+However, if you want more control over serialization and de-serialization,
+you can create a :class:`Pickler` or an :class:`Unpickler` object, respectively.
