      Inside that directory, you can run several commands:
        * npm start: Starts the development server.
        * npm run qa: Run test.
        * npm run ftp: ftp to the test server.
        * npm run build: Bundles the app into dist for production.

      We suggest that you begin by typing:
        cd ${dest}
        npm start
