+isomorphic-fetch [![Build Status](https://travis-ci.org/matthew-andrews/isomorphic-fetch.svg?branch=master)](https://travis-ci.org/matthew-andrews/isomorphic-fetch)
+================
+
+Fetch for node and Browserify.  Built on top of [GitHub's WHATWG Fetch polyfill](https://github.com/github/fetch).
+
+## Warnings
+
+- This adds `fetch` as a global so that its API is consistent between client and server.
+- You must bring your own ES6 Promise compatible polyfill, I suggest [es6-promise](https://github.com/jakearchibald/es6-promise).
+
+## Installation
+
+### NPM
+
+```sh
+npm install --save isomorphic-fetch es6-promise
+```
+
+### Bower
+
+```sh
+bower install --save isomorphic-fetch es6-promise
+```
+
+## Usage
+
+```js
+require('es6-promise').polyfill();
+require('isomorphic-fetch');
+
+fetch('//offline-news-api.herokuapp.com/stories')
+	.then(function(response) {
+		if (response.status >= 400) {
+			throw new Error("Bad response from server");
+		}
+		return response.json();
+	})
+	.then(function(stories) {
+		console.log(stories);
+	});
+```
