+===========
+RMA Account
+===========
+
+This module integrates Return Merchandise Authorizations (RMA) with invoices,
+ allowing to:
+
+#. Create complete RMA's using existing invoices as a reference.
+#. Create refunds from RMA.
+
+Usage
+=====
+
+RMA are accessible though Inventory menu. There's four menus, divided by type
+. Users can access to the list of RMA or RMA lines.
+
+Create an RMA:
+#. Select a partner. Fill the rma lines by selecting an invoice.
+#. Request approval and approve.
+#. Click on RMA Lines button.
+#. Click on more and select an option: "Receive products", "Create Delivery
+   Order, Create Refund".
+#. Go back to the RMA. Set the RMA to done if not further action is required.
+
+
