		Use this command to run a friendly wizard to get started with balena.

		The wizard will guide you through:

			- Create an application.
			- Initialise an SDCard with the balena operating system.
			- Associate an existing project directory with your balena application.
			- Push your project to your devices.

		Examples:

			$ balena quickstart
			$ balena quickstart MyApp
