+================
+Onchange actions
+================
+
+This module allows you to return an action (``ir.actions.*``) from an onchange handler.
+
+Whit way, you can have much more elaborate message boxes or simply show a whole wizard or do whatever else is possible with actions on the client side.
+
+Usage
+=====
+
+Depend on this module and in your onchange handler, add a key ``action`` to the ``warning`` dictionary of the result which contains the definition of an action to execute:
+
+.. code:: python
+
+    {
+        'value': ....,
+        'domain': ....,
+        'warning': {
+            'title': 'This will be shown if this module is not available',
+            'message': 'Fallback message, see above',
+            # this module picks up this key and shows it *instead* of the
+            # warning above
+            'action': {
+                'type': 'ir.actions.act_window',
+                'res_model': 'my.wizard',
+                ...
+            },
+    }
+
+The module ``web_ir_actions_act_window_message`` can be quite helpful here.
