+Create recurring documents.
+===========================
+
+This module allows to create new documents and add recurring on that
+document.
+
+e.g. To have an invoice generated automatically periodically:
+-------------------------------------------------------------
+    * Define a document type based on Invoice object
+    * Define a recurring whose source document is the document defined as
+      above. Specify the interval information and partner to be invoiced.
+      Module taken from odoov10 subscription.
