 Twizy: Drivemode Button Editor
 ==============================
 
+.. image:: drivemode-config.png
+
+This plugin has been added to the Twizy code. It's used here as a more complex
+example of what can be done by plugins.
+
+It's an editor for the drivemode buttons the Twizy adds to the dashboard for
+quick tuning profile changes. The editor allows to change the layout (number
+and order of buttons) and the profiles to use.
+
+It includes a profile selector built with the dialog widget, that retrieves
+the available profiles from the OVMS config store.
+
+**Install**: not necessary if vehicle Twizy is configured (see "Twizy" menu). If
+you'd like to test this for another vehicle, add as a ``page`` plugin e.g. ``/test/dmconfig``.

 Regen Brake Monitor
 ===================
 
+.. image:: regenmon.png
+   :scale: 50%
+   :align: right
+
+This plugin defines a page including an acceleration level gauge chart, number metrics
+for the acceleration, speed and battery power and two large indicators for the
+regen brake light and the brake pedal state.
+
+It's useful to fine tune the regen brake settings, as you can monitor the actual
+deceleration levels while driving and check the smoothing level.
