@@ -0,0 +1,3 @@
+This module extends the functionality of the `stock_inventory` module from the OCA/stock-logistics-warehouse repository to include exhausted products (with zero quantity) in inventory adjustments.
+
+In recent versions of Odoo, when a product reaches zero available quantity, its `stock.quant` is automatically deleted. This module allows creating quants with zero quantity for exhausted products when creating a new inventory adjustment, facilitating the physical counting of these products.

+* **User interface**: Field visible in the inventory adjustment form
