+
+This module provides different configuration option to manage packagings
+on sale orders.
+
+The creation/update of sale order line will be blocked (by constraints)
+if the data on the sale.order.line does not fit with the configuration
+of the product's packagings.
+
+It's also possible to force the quantity to sell during
+creation/modification of the sale order line if the "Force sale
+quantity" is ticked on the packaging and the "Sell only by packaging" is
+ticked on product.
+
+For example, if your packaging is set to sell by 5 units and the
+employee fill the quantity with 3, the quantity will be automatically
+replaced by 5 (it always rounds up).
+
+.. 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.
+   `More details on development status <https://odoo-community.org/page/development-status>`_

+
+Configuration
+=============
+
+Following options are available to define which packaging level can be
+sold and which product can only be sold by packaging.
+
+- Sell only by packaging: On product template model, this checkbox
+  restricts sales of these products if no packaging is selected on the
+  sale order line. If no packaging is selected, it will either be
+  auto-assigned if the quantity on the sale order line matches a
+  packaging quantity or an error will be raised.
+- Force sale quantity (on the packaging): force rounds up the quantity
+  during creation/modification of the sale order line with the factor
+  set on the packaging.
+

+This module provides different configuration option to manage packagings
+on sale orders.
+
+The creation/update of sale order line will be blocked (by constraints)
+if the data on the sale.order.line does not fit with the configuration
+of the product's packagings.
+
+It's also possible to force the quantity to sell during
+creation/modification of the sale order line if the "Force sale
+quantity" is ticked on the packaging and the "Sell only by packaging" is
+ticked on product.
+
+For example, if your packaging is set to sell by 5 units and the
+employee fill the quantity with 3, the quantity will be automatically
+replaced by 5 (it always rounds up).

+<p>This module provides different configuration option to manage packagings
+on sale orders.</p>
+<p>The creation/update of sale order line will be blocked (by constraints)
+if the data on the sale.order.line does not fit with the configuration
+of the product’s packagings.</p>
+<p>It’s also possible to force the quantity to sell during
+creation/modification of the sale order line if the “Force sale
+quantity” is ticked on the packaging and the “Sell only by packaging” is
+ticked on product.</p>
+<p>For example, if your packaging is set to sell by 5 units and the
+employee fill the quantity with 3, the quantity will be automatically
+replaced by 5 (it always rounds up).</p>
