+Classes
+=======
+
+pvlib-python provides a collection of classes for users that prefer
+object-oriented programming. These classes can help users keep track of
+data in a more organized way, and can help to simplify the modeling
+process. The classes do not add any functionality beyond the procedural
+code. Most of the object methods are simple wrappers around the
+corresponding procedural code.
