Operating Options:
	--public-node
		Start Parity as a public web server. Account storage and transaction signing will be delegated to the UI.
	--no-download
		Normally new releases will be downloaded ready for updating. This disables it. Not recommended.
	--no-consensus
		Force the binary to run even if there are known issues regarding consensus. Not recommended.
	--light
		Experimental: run in light client mode. Light clients synchronize a bare minimum of data and fetch necessary data on-demand from the network. Much lower in storage, potentially higher in bandwidth. Has no effect with subcommands.
	--force-direct
		Run the originally installed version of Parity, ignoring any updates that have since been installed.
	--mode=[MODE]
		Set the operating mode. MODE can be one of:
			last - Uses the last-used mode, active if none.
			active - Parity continuously syncs the chain.
			passive - Parity syncs initially, then sleeps and wakes regularly to resync.
			dark - Parity syncs only when the RPC is active.
			offline - Parity doesn't sync. (default: last)
	--mode-timeout=[SECS]
		Specify the number of seconds before inactivity timeout occurs when mode is dark or passive (default: 300)
	--mode-alarm=[SECS]
		Specify the number of seconds before auto sleep reawake timeout occurs when mode is passive (default: 3600)
	--auto-update=[SET]
		Set a releases set to automatically update and install.
			all - All updates in the our release track.
			critical - Only consensus/security updates.
			none - No updates will be auto-installed. (default: critical)
	--release-track=[TRACK]
		Set which release track we should use for updates.
			stable - Stable releases.
			beta - Beta releases.
			nightly - Nightly releases (unstable).
			testing - Testing releases (do not use).
			current - Whatever track this executable was released on (default: current)
