 ## Validation
 
-When deserializing data, you always need to call `is_valid()` before attempting to access the deserialized object.  If any validation errors occur, the `.errors` and `.non_field_errors` properties will contain the resulting error messages.
+When deserializing data, you always need to call `is_valid()` before attempting to access the deserialized object.  If any validation errors occur, the `.errors` property will contain a dictionary representing the resulting error messages.
+Each key in the dictionary will be the field name, and the values will be lists of strings of any error messages corresponding to that field.  The `non_field_errors` key may also be present, and will list any general validation errors.
 
-When deserialising a list of items, errors will be returned as a list of tuples. The first item in an error tuple will be the index of the item with the error in the original data; The second item in the tuple will be a dict with the individual errors for that item.
+When deserializing a list of items, errors will be returned as a list of dictionaries representing each of the deserialized items.
