+::: cowboy
+
+The `cowboy` module provides convenience functions for
+manipulating Ranch listeners.
+
+:: Types
+
+: http_headers() = [{binary(), iodata()}]
+
+HTTP headers as a list of key/values.
+
+: http_status() = non_neg_integer() | binary()
+
+HTTP status.
+
+A binary status can be used to set a custom message.
+
+: http_version() = 'HTTP/1.1' | 'HTTP/1.0'
+
+HTTP version.
+
+: onrequest_fun() = fun((cowboy_req:req()) -> cowboy_req:req())
+
+Fun called immediately after receiving a request.
+
+It can perform any operation on the Req object, including
+reading the request body or replying. If a reply is sent,
+the processing of the request ends here, before any middleware
+is executed.
+
+: onresponse_fun() = fun((http_status(), http_headers(),
+	iodata(), cowboy_req:req()) -> cowboy_req:req())
+
+Fun called immediately before sending the response.
+
+It can perform any operation on the Req object, including
+reading the request body or replying. If a reply is sent, it
+overrides the reply initially sent. The callback will not be
+called again for the new reply.
+
+:: Exports
+
+: start_http(Ref, NbAcceptors, TransOpts, ProtoOpts) -> {ok, pid()}
+
+Types:
+
+* Ref = ranch:ref()
+* NbAcceptors = non_neg_integer()
+* TransOpts = ranch_tcp:opts()
+* ProtoOpts = cowboy_protocol:opts()
+
+Start listening for HTTP connections. Returns the pid for this
+listener's supervisor.
+
+: start_https(Ref, NbAcceptors, TransOpts, ProtoOpts) -> {ok, pid()}
+
+Types:
+
+* Ref = ranch:ref()
+* NbAcceptors = non_neg_integer()
+* TransOpts = ranch_ssl:opts()
+* ProtoOpts = cowboy_protocol:opts()
+
+Start listening for HTTPS connections. Returns the pid for this
+listener's supervisor.
+
+: start_spdy(Ref, NbAcceptors, TransOpts, ProtoOpts) -> {ok, pid()}
+
+Types:
+
+* Ref = ranch:ref()
+* NbAcceptors = non_neg_integer()
+* TransOpts = ranch_ssl:opts()
+* ProtoOpts = cowboy_spdy:opts()
+
+Start listening for SPDY connections. Returns the pid for this
+listener's supervisor.
+
+: stop_listener(Ref) -> ok | {error, not_found}
+
+Types:
+
+* Ref = ranch:ref()
+
+Stop a previously started listener.
+
+: set_env(Ref, Name, Value) -> ok
+
+Types:
+
+* Ref = ranch:ref()
+* Name = atom()
+* Value = any()
+
+Set or update an environment value for an already running listener.
+This will take effect on all subsequent connections.
