+
+Lightweight ES6 Promise polyfill for the browser and node. Adheres closely to
+the spec. It is a perfect polyfill IE, Firefox or any other browser that does
+not support native promises.
+
+For API information about Promises, please check out this article
+[HTML5Rocks article](http://www.html5rocks.com/en/tutorials/es6/promises/).
+
+It is extremely lightweight. **_< 1kb Gzipped_**

+```
+
+## Downloads
+
+* [Promise](https://raw.github.com/taylorhakes/promise-polyfill/master/dist/promise.js)
+* [Promise-min](https://raw.github.com/taylorhakes/promise-polyfill/master/dist/promise.min.js)
+
+## Simple use
+
+```js
+import Promise from 'promise-polyfill';
+```
+
+then you can use like normal Promises
+
+```js
+var prom = new Promise(function(resolve, reject) {
+  // do a thing, possibly async, then…
+
+  if (/* everything turned out fine */) {
+    resolve("Stuff worked!");
+  }  else {
+    reject(new Error("It broke"));
+  }
+});
+
+prom.then(function(result) {
+  // Do something when async done
+});
+```
+
+If you would like to just polyfill, only if native doesn't exist.
+
+```js
+import 'promise-polyfill/src/polyfill';
+```
+
+## Performance
+
+By default promise-polyfill uses `setImmediate`, but falls back to `setTimeout`
+for executing asynchronously. If a browser does not support `setImmediate`
+(IE/Edge are the only browsers with setImmediate), you may see performance
+issues. Use a `setImmediate` polyfill to fix this issue.
+[setAsap](https://github.com/taylorhakes/setAsap) or
+[setImmediate](https://github.com/YuzuJS/setImmediate) work well.
+
+If you polyfill `window.setImmediate` or use `Promise._immediateFn = yourImmediateFn` it will be used instead of `window.setTimeout`
+
+```
+npm install setasap --save
+```
+
+```js
+import Promise from 'promise-polyfill/src/polyfill';
+import setAsap from 'setasap';
+Promise._immediateFn = setAsap;
+```
+
+## Unhandled Rejections
+
+promise-polyfill will warn you about possibly unhandled rejections. It will show
+a console warning if a Promise is rejected, but no `.catch` is used. You can
+change this behavior by doing.
+
+```js
+Promise._unhandledRejectionFn = <your reject error handler>;
+```
+
+If you would like to disable unhandled rejection messages. Use a noop like
+below.
+
+```js
+Promise._unhandledRejectionFn = function(rejectError) {};
+```
+
+## Testing
+
+```
+npm install
+npm test
+```
