		Use this command to update the Resin CLI

		This command outputs information about the update process.
		Use `--quiet` to remove that output.

		The Resin CLI checks for updates once per day.

		Major updates require a manual update with this update command,
		while minor updates are applied automatically.

		Examples:

			$ resin update
