  Now a name. Naming things is hard 😬

  We'd appreciate if you pick:

   - a firstname like ${chalk.green('alex')}, ${chalk.green('jordan')}, ${chalk.green('ezra')}, or ${chalk.green('logan')}
   - that is an aliteration with the kind of design, like ${chalk.green('wahid')} for a ${chalk.green('w')}aistcoat

   Bonus points for picking a name that embraces diversity 🌈 ✊

  👉  We've created your design skeleton at ${chalk.green('designs/'+name)}
  👉  We've configured the packages via the ${chalk.green('pacakge.json')} file
  👉  We've added ${chalk.green('designs/'+name)} to the lab


  ${chalk.bold.yellow('✏️  Make it your own')}
  ${chalk.gray('≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡')}

  Hhere's a few other things you can configure:

  👉 ${chalk.yellow('Author')}: Credit where credit is due; Add yourself as author in ${chalk.green('config/exceptions.yaml')}
  👉 ${chalk.yellow('Description')}: We used a placeholder description; Update it in ${chalk.green('config/software/designs.json')}
  👉 ${chalk.yellow('Dependencies')}: If you need additional plugins or patterns to extend, update ${chalk.green('config/dependecies.yaml')}

  If you change any of these, run ${chalk.blue('yarn reconfigure')} to update the package(s).


  ${chalk.bold.yellow('👷 Get to work')}
  ${chalk.gray('≡≡≡≡≡≡≡≡≡≡≡≡≡≡')}

  🛠️   You can now start the development environment with ${chalk.blue('yarn lab')}
  📖  Documentation is available at ${chalk.green('https://freesewing.dev/')}
  🤓  Happy hacking
