+This module was written to extend the functionality of odoo pos
+and allows you to require a customer for each pos order.  In the
+pos session configuration, you can choose to require the customer for pos
+orders.
+
+If a customer is not selected, the pos ui will display an error message.
+In the backend the customer field is required when needed.
+
+Two new options are available:
+
+* Customer 'Required before starting the order';
+* Customer 'Required before paying';
+
+'Required before starting the order' Option
+-------------------------------------------
+In the frontend PoS, the default screen is the screen to select customers.
+
+* Users are not allowed to start selling before having selected a customer;
+* Users can not 'deselect a customer', only select an other one;
+
+'Required before paying' Option
+-------------------------------
+In the frontend PoS, the user can start selling, but if the user tries to
+make payment and if a customer is not selected, the pos ui will display an
+error message.
