+Contracts for recurrent sales
+=============================
+
+This module extends functionality of contracts to be able to generate sales 
+orders instead of invoices.
+
+Usage
+=====
+
+To use this module, you need to:
+
+#. Go to Accounting -> Contracts and select or create a new contract.
+#. Check *Generate recurring invoices automatically*.
+#. Fill fields for selecting the recurrency and invoice parameters:
+
+   * Type defines document that contract will generate, can be "Sales" or "Invoices"
+   * Sale Autoconfirm, validate Sales Orders if type is "Sales"
