+# Web Component Twig Extension
+
+The web component twig extension in connection with [web-js](https://github.com/massiveart/web-js) 
+gives you simple and efficient way to handle your javascript components over twig.
+
+## Setup
+
+### Service Registration
+
+The twig extension need to be registered as [symfony service](http://symfony.com/doc/current/service_container.html).
+
+**xml**
+
+```xml
+<?xml version="1.0" encoding="UTF-8" ?>
+<container xmlns="http://symfony.com/schema/dic/services"
+    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
+    xsi:schemaLocation="http://symfony.com/schema/dic/services
+        http://symfony.com/schema/dic/services/services-1.0.xsd">
+
+    <services>
+        <service id="app.web_components" class="Massive\Component\Web\ComponentTwigExtension">
+            <tag name="twig.extension" />
+        </service>
+    </services>
+</container>
+```
+
+**yml**
+
+```yml
+services:
+    app.web_components:
+        class: Massive\Component\Web\ComponentTwigExtension
+        tags:
+            - { name: twig.extension }
+```
+
+## Usage
+
+You can get the registered components and service call and call the
+[web-js](https://github.com/massiveart/web-js) function which is recommended to be used with it.
+
+```twig
+{# Registering a component #}
+<div id="{{ register_component('component') }}">
+    Content
+</div>
+
+{# Registering a component with options #}
+<button id="{{ register_component('modal-button', { text: 'Hello Hikaru Sulu' }) }}">
+    Say Hello
+</button>
+
+{# Call a service function #}
+{{ call_service('service', 'function') }}
+
+{# Call a service function with arguments #}
+{{ call_service('api', 'send', ['Hello']) }}
+
+{# Start components and run service functions #}
+<script>
+    web.startComponents({{ get_components() }});
+    web.callServices({{ get_services() }});
+</script>
+```
