      This means I didn't find a _templates folder right here, 
      or anywhere up the folder tree starting here.

      Here's how to start using Hygen:

      $ hygen init self
      $ hygen with-prompt new --name my-generator

      (edit your generator in _templates/my-generator)

      $ hygen my-generator 

      See http://hygen.io for more.
      
      `);
    return;
  }

  Object.entries(availableActions(templates)).forEach(([k, v]) => {
    logger.log(`${chalk.bold(k)}: ${v.join(', ')}`);
  });
};

module.exports = {
  availableActions,
  printHelp
};
