+These workers are compatible with Python 3.
 
 The worker `gthread` is a threaded worker. It accepts connections in the
 main loop, accepted connections are added to the thread pool as a
 connection job. On keepalive connections are put back in the loop
 waiting for an event. If no event happen after the keep alive timeout,
 the connection is closed.

-   The ``gaiohttp`` worker requires the aiohttp_ module to be installed.

-   If you want to continue to use the ``gaiohttp`` worker with your WSGI

-
-   #. Install aiohttp_ version 1.3.5 instead of version 2::

-   #. Use aiohttp_wsgi_ to wrap your WSGI application. You can take a look
-      at the `example`_ in the Gunicorn repository.
-   #. Port your application to use aiohttp_'s ``web.Application`` API.
-   #. Use the ``aiohttp.worker.GunicornWebWorker`` worker instead of the
