Use the --help flag:

% daphne --help
usage: daphne [-h] [-p PORT] [-b HOST] [--websocket_timeout WEBSOCKET_TIMEOUT]
              [--websocket_connect_timeout WEBSOCKET_CONNECT_TIMEOUT]
              [-u UNIX_SOCKET] [--fd FILE_DESCRIPTOR] [-e SOCKET_STRINGS]
              [-v VERBOSITY] [-t HTTP_TIMEOUT] [--access-log ACCESS_LOG]
              [--log-fmt LOG_FMT] [--ping-interval PING_INTERVAL]
              [--ping-timeout PING_TIMEOUT]
              [--application-close-timeout APPLICATION_CLOSE_TIMEOUT]
              [--root-path ROOT_PATH] [--proxy-headers]
              [--proxy-headers-host PROXY_HEADERS_HOST]
              [--proxy-headers-port PROXY_HEADERS_PORT] [-s SERVER_NAME]
              [--no-server-name]
              application

Django HTTP/WebSocket server

positional arguments:
  application           The application to dispatch to as
                        path.to.module:instance.path

options:
  -h, --help            show this help message and exit
  -p PORT, --port PORT  Port number to listen on
  -b HOST, --bind HOST  The host/address to bind to
  --websocket_timeout WEBSOCKET_TIMEOUT
                        Maximum time to allow a websocket to be connected. -1
                        for infinite.
  --websocket_connect_timeout WEBSOCKET_CONNECT_TIMEOUT
                        Maximum time to allow a connection to handshake. -1
                        for infinite
  -u UNIX_SOCKET, --unix-socket UNIX_SOCKET
                        Bind to a UNIX socket rather than a TCP host/port
  --fd FILE_DESCRIPTOR  Bind to a file descriptor rather than a TCP host/port
                        or named unix socket
  -e SOCKET_STRINGS, --endpoint SOCKET_STRINGS
                        Use raw server strings passed directly to twisted
  -v VERBOSITY, --verbosity VERBOSITY
                        How verbose to make the output
  -t HTTP_TIMEOUT, --http-timeout HTTP_TIMEOUT
                        How long to wait for worker before timing out HTTP
                        connections
  --access-log ACCESS_LOG
                        Where to write the access log (- for stdout, the
                        default for verbosity=1)
  --log-fmt LOG_FMT     Log format to use
  --ping-interval PING_INTERVAL
                        The number of seconds a WebSocket must be idle before
                        a keepalive ping is sent
  --ping-timeout PING_TIMEOUT
                        The number of seconds before a WebSocket is closed if
                        no response to a keepalive ping
  --application-close-timeout APPLICATION_CLOSE_TIMEOUT
                        The number of seconds an ASGI application has to exit
                        after client disconnect before it is killed
  --root-path ROOT_PATH
                        The setting for the ASGI root_path variable
  --proxy-headers       Enable parsing and using of X-Forwarded-For and
                        X-Forwarded-Port headers and using that as the client
                        address
  --proxy-headers-host PROXY_HEADERS_HOST
                        Specify which header will be used for getting the host
                        part. Can be omitted, requires --proxy-headers to be
                        specified when passed. "X-Real-IP" (when passed by
                        your webserver) is a good candidate for this.
  --proxy-headers-port PROXY_HEADERS_PORT
                        Specify which header will be used for getting the port
                        part. Can be omitted, requires --proxy-headers to be

  -s SERVER_NAME, --server-name SERVER_NAME
                        specify which value should be passed to response
