+*********************
+OVSDB Manager library
+*********************
+
+Introduction
+============
+
+Ryu OVSDB Manager library allows your code to interact with devices
+speaking the OVSDB protocol. This enables your code to perform remote
+management of the devices and react to topology changes on them.
+
+Example
+=======
+
+The following logs all new OVSDB connections and allows creating a port
+on a bridge.
+
+.. code-block:: python
+
+    import uuid
+
+    from ryu.base import app_manager
+    from ryu.services.protocols.ovsdb import api as ovsdb
+    from ryu.services.protocols.ovsdb import event as ovsdb_event
+
+
+    class MyApp(app_manager.RyuApp):
+        @set_ev_cls(ovsdb_event.EventNewOVSDBConnection)
+        def handle_new_ovsdb_connection(self, ev):
+            system_id = ev.system_id
+            self.logger.info('New OVSDB connection from system id %s',
+                             systemd_id)
+
+        def create_port(self, systemd_id, bridge_name, name):
+            new_iface_uuid = uuid.uuid4()
+            new_port_uuid = uuid.uuid4()
+
+            def _create_port(tables, insert):
+                bridge = ovsdb.row_by_name(self, system_id, bridge_name)
+
+                iface = insert(tables['Interface'], new_iface_uuid)
+                iface.name = name
+                iface.type = 'internal'
+
+                port = insert(tables['Port'], new_port_uuid)
+                port.name = name
+                port.interfaces = [iface]
+
+                brdige.ports = bridfe.ports + [port]
+
+                return (new_port_uuid, new_iface_uuid)
+
+            req = ovsdb_event.EventModifyRequest(system_id, _create_port)
+            rep = self.send_request(req)
+
+            if rep.status != 'success':
+                self.logger.error('Error creating port %s on bridge %s: %s',
+                                  name, bridge, rep.status)
+                return None
+
+            return reply.insert_uuid[new_port_uuid]
