  ${chalk.green('Awesome!')} You're now ready to start coding.
  
  I already ran ${Output.cmd(commands.install)} for you, so your next steps are:
    ${Output.cmd(`cd ${projectName}`)}
  
  To start developing (rebuilds on changes):
    ${Output.cmd(commands.start)}
  
  To build for production:
    ${Output.cmd(commands.build)}

  To test your library with Jest:
    ${Output.cmd(commands.test)}
