 Defining Callbacks
 ==================
 
-You specify the callbacks by first creating a new class method in your model to use. This class will always
-receive a ``$data`` array as its only parameter. The exact contents of the ``$data`` array will vary between events, but
-will always contain a key named **data** that contains the primary data passed to the original method. In the case
-of the insert* or update* methods, that will be the key/value pairs that are being inserted into the database. The
-main array will also contain the other values passed to the method, and be detailed later. The callback method
-must return the original $data array so other callbacks have the full information.
