+# Vanilla ES6 (ES2015) • [TodoMVC](http://todomvc.com)
+
+> An exact port of the [Vanilla JS Example](http://todomvc.com/examples/vanillajs/), but translated into ES6, also known as ES2015.
+
+## Learning ES6
+
+- [ES6 Features](https://github.com/lukehoban/es6features)
+- [Learning Resources](https://github.com/ericdouglas/ES6-Learning)
+- [Babel's ES6 Guide](https://babeljs.io/docs/learn-es2015/)
+- [Babel Compiler](https://babeljs.io/)
+
+## Installation
+
+To get started with this example, navigate into the example folder and install the NPM modules.
+```bash
+cd todomvc/examples/vanilla-es6
+npm install
+```
+
+## Compiling ES6 to ES5
+
+After NPM modules have been installed, use the pre-defined Babel script to convert the `src` files. Browserify is also used so that `module.exports` and `require()` can be run in your browser.
+
+```bash
+npm run compile
+```
+
+## Support

+*Let us [know](https://github.com/tastejs/todomvc/issues) if you discover anything worth sharing.*
+
+
+## Implementation
+
+Uses [Babel JS](https://babeljs.io/) to compile ES6 code to ES5, which is then readable by all browsers.
