 Timeline Widget
 ===============
 
-!Prototype!
 Define a new widget displaying events in an interactive visualization chart.
+
 The widget is based on the external library 
 http://visjs.org/timeline_examples.html
+
+Usage
+=====
+
+Example:
+    <?xml version="1.0" encoding="utf-8"?>
+    <openerp>
+        <data>
+    
+            <record id="view_task_timeline" model="ir.ui.view">
