+AioPika as a pubsub
+~~~~~~~~~~~~~~~~~~~
+
+If you want to combine a RabbitMQ based manager with asyncio and a
+:class:`socketio.AsyncServer` class, you can use the
+`AioPika <https://aio-pika.readthedocs.io/en/latest/>`_ based manager.
+You need to install aio_pika with pip::
+
+    pip install aio_pika
+
+The RabbitMQ queue is configured through the
+:class:`socketio.AsyncPubSubAioPikaManager`::
+
+    mgr = socketio.AsyncPubSubAioPikaManager('amqp://')
+    sio = socketio.AsyncServer(client_manager=mgr)
+
+AioPika as task queue
+~~~~~~~~~~~~~~~~~~~~~
+
+Using a pubsub manager does not guarantee message delivery, in the case where a
+client you want to deliver a message to is disconnected during the publication
+of the event. When this client reconnects, the message was already published,
+so it will miss it.
+Using a task queue by client to publish this message will solve this use case.
+This comes with a limitation: you have to publish the message once for each
+client you want to deliver it to, which is inconvenient if you need to dispatch
+messages to multiple clients at once.
+
+You can use RabbitMQ as a task queue with
+:class:`socketio.AsyncTaskQueueAioPikaManager`::
+
+    mgr = socketio.AsyncTaskQueueAioPikaManager('amqp://')
+    sio = socketio.AsyncServer(client_manager=mgr)
+
+Then, you can register tasks to this manager to start listening for events to
+emit to a specific client, for example::
+
+    @sio.event
+    async def connect(sid, environ):
+        mgr.register_task('some token to uniquely identify your client')
+
+    @sio.event
+    async def disconnect(sid):
+        mgr.cancel_task('some token to uniquely identify your client')
+
+You can them emit events to this client::
+
+    mgr.emit('event', data='data',
+             task_queue='some token to uniquely identify your client',
+             room='room', namespace='namespace')
+
+The event will be emitted even if the client is currently disconnected but
+reconnects later.
