## Use NPM to install RippleAPI and dependencies ##
RippleAPI uses the newest version of JavaScript, ECMAScript 6 (also known as ES2015). To use the new features of ECMAScript 6, RippleAPI depends on [Babel-Node](https://babeljs.io) and its ES2015 presets. You can use `npm` to install RippleAPI and these dependencies together.
