  To set up this project you need to provide your Space ID
  and the belonging API access tokens.
  You can find all the needed information in your Contentful space under:
  ${chalk.yellow(

  )}
  The ${chalk.green('Content Management API Token')}
    will be used to import and write data to your space.
  The ${chalk.green('Content Delivery API Token')}
    will be used to ship published production-ready content in your Gatsby app.
  The ${chalk.green('Content Preview API Token')}
    will be used to show not published data in your development environment.
  Ready? Let's do it! 🎉
