+# Événement
+
+Événement is a very simple event dispatching library for PHP.
+
+It has the same design goals as [Silex](https://silex.symfony.com/) and
+[Pimple](https://github.com/silexphp/Pimple), to empower the user while staying concise
+and simple.
+
+It is very strongly inspired by the [EventEmitter](https://nodejs.org/api/events.html#events_class_eventemitter) API found in
+[node.js](http://nodejs.org).
+
+![Continuous Integration](https://github.com/igorw/evenement/workflows/CI/badge.svg)
+[![Latest Stable Version](https://poser.pugx.org/evenement/evenement/v/stable.png)](https://packagist.org/packages/evenement/evenement)
+[![Total Downloads](https://poser.pugx.org/evenement/evenement/downloads.png)](https://packagist.org/packages/evenement/evenement/stats)
+[![License](https://poser.pugx.org/evenement/evenement/license.png)](https://packagist.org/packages/evenement/evenement)
+
+## Fetch
+
+The recommended way to install Événement is [through composer](http://getcomposer.org). By running the following command:
+

+### Adding Listeners
+
+```php
+<?php
+$emitter->on('user.created', function (User $user) use ($logger) {
+    $logger->log(sprintf("User '%s' was created.", $user->getLogin()));
+});
+```
+
+### Removing Listeners
+
+```php
+<?php
+$emitter->removeListener('user.created', function (User $user) use ($logger) {
+    $logger->log(sprintf("User '%s' was created.", $user->getLogin()));
+});
+```
+
+### Emitting Events
+
+```php
