${colors.bold(`snowpack`)} - A faster build system for the modern web.

  Snowpack is best configured via config file.
  But, most configuration can also be passed via CLI flags.
  📖 ${colors.dim('https://www.snowpack.dev/reference/configuration')}

${colors.bold('Commands:')}
  snowpack init          Create a new project config file.
  snowpack prepare       Prepare your project for development (optional).
  snowpack dev           Develop your project locally.
  snowpack build         Build your project for production.
  snowpack add [package] Add a package to your project.
  snowpack rm [package]  Remove a package from your project.

${colors.bold('Flags:')}
  --config [path]        Set the location of your project config file.
  --help                 Show this help message.
  --version              Show the current version.
  --reload               Clear the local cache (useful for troubleshooting).
  --cache-dir-path       Specify a custom cache directory.
  --verbose              Enable verbose log messages.
  --quiet                Enable minimal log messages.
