+Documentation
+====
+
+This package integrates [symfony/event-dispatcher](https://github.com/symfony/event-dispatcher) to Nette Framework.
+
+Installation
+----
+
+The best way to install Arachne/EventDispatcher is using [Composer](http://getcomposer.org/).
+
+```sh
+$ composer require arachne/event-dispatcher
+```
+
+Now add these extensions to your config.neon.
+
+```yml
+extensions:
+    arachne.containeradapter: Arachne/ContainerAdapter/DI/ContainerAdapterExtension
+    arachne.eventdispatcher: Arachne/EventDispatcher/DI/EventDispatcherExtension
+```
+
+See the documentation of [symfony/event-dispatcher](http://symfony.com/doc/current/components/event_dispatcher/index.html) for details.
+
+Subscribers
+----
+
+To add register an event subscriber, add it to your config.neon.
+
+```
+services:
+    subscriber:
+        class: App\AdminModule\Event\Subscriber
+        tags:
+            - arachne.eventDispatcher.subscriber
+```
+
+You can also simplify it using the DecoratorExtension from Nette.
+
+```
+decorator:
+    Symfony\Component\EventDispatcher\EventSubscriberInterface:
+        tags:
+            - arachne.eventDispatcher.subscriber
+
+services:
+    subscriber: App\AdminModule\Event\Subscriber
+```
+
+Application events
+----
+
+If you're using [nette/application](https://github.com/nette/application) the events in `Nette/Application/Application` will be fired by the event dispatcher as well. See the [ApplicationEvents](../src/ApplicationEvents.php) class for details.
