It will automatically create a folder and install all the dependencies it needs.

once the setup is completed you can navigate into that folder with command cd burger-builder
And after that simply run the command

npm start

After the command is initeated the browser will be open with the link http://localhost:3000/. this is the development server which loads our react app on port :3000 and reload the page when ever we change the code(file).
