+Open Networking Operating System (ONOS) ML2 MechanismDriver
+==========================================================
+ONOS is a carrier grade SDN open operating system designed for
+High Availability, scale-out and better performance.
+
+ http://www.onosproject.org/
+
+Mode of Working:
+================
+The networking-onos project provides a thin layer which makes the
+communication between ONOS and openstack neutron possible via ReST
+call. The driver code can be downloaded from:
+
+ https://git.openstack.org/cgit/openstack/networking-onos
+
+Using ONOS ML2 MechanismDriver
+==============================
+To use ONOS ML2 MechanismDriver one should
+1. Make sure networking-onos code is downloaded and installed. If doing
+ mannually then download the code, go inside networking_onos folder
+ and finally run "sudo python setup.py install" otherwise install
+ using pip.
+
+2. Configure ONOS as the required ML2 "mechanism_drivers" in
+ neutron/plugins/ml2/ml2_conf.ini:
+
+ mechanism_drivers=onos
+
+3. Configure "[ml2_onos]" in networking_onos/etc/ml2_onos_conf.ini \ No newline at end of file
