+
+This module bridges ``product_catalog_sale`` with ``sale_rental`` so that
+products added from the catalog on a rental order create proper rental lines.
+
+Without this module, the catalog creates regular sale order lines missing
+``rental_type``, ``rental_qty`` and dates. This module overrides
+``_update_order_line_info`` to automatically set these fields using the
+order's default start and end dates.
+
+The catalog quantity represents the number of items to rent (``rental_qty``),
+and ``product_uom_qty`` is computed as ``rental_qty × number_of_days``.
+
+.. IMPORTANT::
+   This is an alpha version, the data model and design can change at any time without warning.
+   Only for development or testing purpose, do not use in production.
