+============================
+
+This module adds a signature field to contract report.
+
+Installation
+============
+
+This module depends on :
+
+* web_widget_digitized_signature
+
+This module is part of the OCA/web suite.
+
+Usage
+=====
+
+#. Go to **Sales > Sales > Contracts** and edit or create a contract.
+#. You will see a box ready to write a signature by your customer.
+#. Save Contract.
