 ==============
-Sale Exception
+Base Exception
 ==============
 
-This module allows you attach several customizable exceptions to your
-sale order in a way that you can filter orders by exceptions type and fix them.
-
-This is especially useful in an scenario for mass sales order import such as 
-with the base_sale_multi_channels module, because it's likely some orders have
-errors when you import them (like product not found in Odoo, wrong line
-format etc.)
+This module provide an abstract model to manage customizable exceptions to be applied on different models (sale order, invoice, ...). It is not usefull for itself. You can see an exemple of implementation in the 'sale_exception' module. (sale-workflow repository).
