+This directory contains examples that demonstrate how to use the QMenuModel
+QML binding in applications.
+
+To export an example menu model on the bus, run 'exportmenu.py'.
+
+To render this menu in a QML application, run 'render-menumodel.qml' in
+qmlviewer. You will need to inform qmlviewer of the location of the QMenuModel
+if it’s not installed system-wide, e.g.:
+
+ qmlviewer -I src examples/render-menumodel.qml
