+# ES6-Promise (subset of [rsvp.js](https://github.com/tildeio/rsvp.js))
+
+This is a polyfill of the [ES6 Promise](http://people.mozilla.org/~jorendorff/es6-draft.html#sec-promise-constructor). The implementation is a subset of [rsvp.js](https://github.com/tildeio/rsvp.js), if you're wanting extra features and more debugging options, check out the [full library](https://github.com/tildeio/rsvp.js).
+
+For API details and how to use promises, see the <a href="http://www.html5rocks.com/en/tutorials/es6/promises/">JavaScript Promises HTML5Rocks article</a>.

+* [es6-promise-min](https://raw.githubusercontent.com/jakearchibald/es6-promise/master/dist/es6-promise.min.js)
+
+## Node.js
+
+To install:
+
+```sh
+npm install es6-promise
+```
+
+To use:
+
+```js
+var Promise = require('es6-promise').Promise;
+```
+
+## Usage in IE<9
+
+`catch` is a reserved word in IE<9, meaning `promise.catch(func)` throws a syntax error. To work around this, you can use a string to access the property as shown in the following example.
+
+However, please remember that such technique is already provided by most common minifiers, making the resulting code safe for old browsers and production:
+
+```js
+promise['catch'](function(err) {
+  // ...
+});
+```
+
+Or use `.then` instead:
+
+```js
+promise.then(undefined, function(err) {
+  // ...
+});
+```
+
+## Auto-polyfill
+
+To polyfill the global environment (either in Node or in the browser via CommonJS) use the following code snippet:
+
+```js
+require('es6-promise').polyfill();
+```
+
+Notice that we don't assign the result of `polyfill()` to any variable. The `polyfill()` method will patch the global environment (in this case to the `Promise` name) when called.
+
+## Building & Testing
+
+* `npm run build` to build
+* `npm test` to run tests
+* `npm start` to run a build watcher, and webserver to test 
+* `npm run test:server` for a testem test runner and watching builder
