-d --datadir PATH Specify the database & configuration directory path [default: $HOME/.parity]
--identity NAME Specify your node's name.
Networking Options:
--no-bootstrap Don't bother trying to connect to any nodes initially.
--listen-address URL Specify the IP/port on which to listen for peers [default: 0.0.0.0:30304].
