+[![Sauce Test Status](https://saucelabs.com/browser-matrix/eventemitter3.svg)](https://saucelabs.com/u/eventemitter3)
+
+EventEmitter3 is a high performance EventEmitter. It has been micro-optimized
+for various of code paths making this, one of, if not the fastest EventEmitter
+available for Node.js and browsers. The module is API compatible with the
+EventEmitter that ships by default with Node.js but there are some slight
+differences:
+
+- Domain support has been removed.
+- We do not `throw` an error when you emit an `error` event and nobody is
+  listening.
+- The `newListener` and `removeListener` events have been removed as they
+  are useful only in some uncommon use-cases.
+- The `setMaxListeners`, `getMaxListeners`, `prependListener` and
+  `prependOnceListener` methods are not available.
+- Support for custom context for events so there is no need to use `fn.bind`.
+- The `removeListener` method removes all matching listeners, not only the
+  first.
+
+It's a drop in replacement for existing EventEmitters, but just faster. Free
+performance, who wouldn't want that? The EventEmitter is written in EcmaScript 3
+so it will work in the oldest browsers and node versions that you need to
+support.
+
+## Installation
+
+```bash
+$ npm install --save eventemitter3
+```
+
+## CDN
+
+Recommended CDN:
+
+```text
+https://unpkg.com/eventemitter3@latest/umd/eventemitter3.min.js
+```
+
+## Usage
+
+After installation the only thing you need to do is require the module:
+
+```js
+var EventEmitter = require('eventemitter3');
+```
+
+And you're ready to create your own EventEmitter instances. For the API
+documentation, please follow the official Node.js documentation:
+
+http://nodejs.org/api/events.html
+
+### Contextual emits
+
+We've upgraded the API of the `EventEmitter.on`, `EventEmitter.once` and
+`EventEmitter.removeListener` to accept an extra argument which is the `context`
+or `this` value that should be set for the emitted events. This means you no
+longer have the overhead of an event that required `fn.bind` in order to get a
+custom `this` value.
+
+```js
+var EE = new EventEmitter()
+  , context = { foo: 'bar' };
+
+function emitted() {
+  console.log(this === context); // true
+}
+
+EE.once('event-name', emitted, context);
+EE.on('another-event', emitted, context);
+EE.removeListener('another-event', emitted, context);
+```
+
+### Tests and benchmarks
+
+This module is well tested. You can run:
+
+- `npm test` to run the tests under Node.js.
+- `npm run test-browser` to run the tests in real browsers via Sauce Labs.
+
+We also have a set of benchmarks to compare EventEmitter3 with some available
+alternatives. To run the benchmarks run `npm run benchmark`.
+
+Tests and benchmarks are not included in the npm package. If you want to play
+with them you have to clone the GitHub repository.
+Note that you will have to run an additional `npm i` in the benchmarks folder
+before `npm run benchmark`.
