+
+This module is abstract and can't be used as is.
+
+It provides functions in order to show a product grid from another model.
+You can then add products and quantities in batch to the model you are working with.
+
+It is useful when you don't want to add every product line possible to your object.
+From the product grid you only have to set the quantity for each product.
+
+Example implementations:
+ - purchase_quick
+ - stock_picking_quick

+
+Known issues / Roadmap
+======================
+
+The module uses Form emulation from backend.
+Once onchange_helper is stabilized, we should switch to it
+because it is more robust and has better perfs.
+
+Also adding new implementations would be great:
+on sale.order or on stock.picking.batch for instance.
