+Usage
+=====
+
+To use this module, you need to:
+
+- Go to Sales > Orders > Quotations
+
+- Create a quotation. Set a customer, a product and a payment term.
+
+- Confirm the quotation.
+
+- Create a second quotation with the same data as above and set a
+  different payment term.
+
+- Confirm the second quotation.
+
+- Go back to the Quotations list view and select the two newly created
+  sales orders.
+
+- Click on the Action button and select Create Invoices.
+
+- In the wizard click on Create and View Invoice.
+
+- Even though both quotations have almost the same data, the invoicing
+  has been split into two invoices because they have different payment
+  terms.
