Install Node and NPM on your machine; this typically requires administrative access,
e.g. become root or use sudo (or use a Windows installer).
You must be running at least Node 4.x.x and npm 3.x.x. You can verify
what, if any, versions you have installed by running node -v and
npm -v in a terminal window.
You can download current versions of these tools here.
If you use a Linux-like environment, you are encouraged to use your package manager to install these tools.
If you use OS X, you may wish to consider installing via HomeBrew.
$ npm install
Run $ npm start for a dev server. Navigate to http://localhost:3000/. The app will automatically reload if you change any of the source files.
Run $ npm run build to build the project. The build artifacts will be stored in the dist/ directory.
