+Sale Project Fixed Price Task Completed Invoicing
+=================================================
+
+The main goal of this module is to add the possibility to link a sale.order.line
+to a project.task considering the delivery.
+Unless sale_timesheet, the quantity shipped won't be linked to a Timesheet nor
+to the time spent on the task. The price is fixed on the sale.order.line and it
+will be considered as shipped once the task is accomplished.
+
+Usage
+=====
+
+Create a product with product.type 'Service' and track_service 'Completed Task'.
+
+Use it in a Sale Order. Once you validate the Sale Order, it will create a linked
+project and task.
+
+Once the task is finished, on the form view of the corrisponding task click on the
+button 'Invoiceable'. The linked sale.order.line will be considered as shipped.
+
+
+Bug Tracker
+===========
+
+Bugs are tracked on `GitHub Issues <https://github.com/OCA/sale-workflow/issues>`_.
+In case of trouble, please check there if your issue has already been reported.
+If you spotted it first, help us smashing it by providing a detailed and welcomed feedback.
