-##[ This module implements a high performance asynchronous HTTP server.
-
-This HTTP server has not been designed to be used in production, but
-for testing applications locally. Because of this, when deploying your
-application in production you should use a reverse proxy (for example nginx)
-instead of allowing users to connect directly to this server.
-
-Basic usage
-===========
-
-This example will create an HTTP server on port 8080. The server will
-respond to all requests with a ``200 OK`` response code and "Hello World"
-as the response body.
