+Installation
+============
+
+Step 1: Download the Bundle
+---------------------------
+
+Open a command console, enter your project directory and execute the
+following command to download the latest stable version of this bundle:
+
+```bash
+$ composer require khill/lavacharts "~3.0"
+```
+
+This command requires you to have Composer installed globally, as explained
+in the [installation chapter](https://getcomposer.org/doc/00-intro.md)
+of the Composer documentation.
+
+Step 2: Enable the Bundle
+-------------------------
+
+Then, enable the bundle by adding it to the list of registered bundles
+in the `app/AppKernel.php` file of your project:
+
+```php
+<?php
+// app/AppKernel.php
+
+// ...
+class AppKernel extends Kernel
+{
+    public function registerBundles()
+    {
+        $bundles = array(
+            // ...
+
+            new Khill\Lavacharts\Symfony\Bundle\LavachartsBundle(),
+        );
+
+        // ...
+    }
+
+    // ...
+}
+```
+
+Step 3: Import the Service
+-------------------------
+
+Lastly, import the service by adding the `services.yml` to the imports
+in the `app/config/config.yml` file of your project:
+
+```php
+imports:
+    // ...
+
+    - { resource: "@LavachartsBundle/Resources/config/services.yml" }
+
+```
+
+Step 4: Pull from the Container
+-------------------------
+
+Now you can use Lavacharts from within your controller:
+
+```php
+    $lava = $this->get('lavacharts');
+
+    $datatable = $lava->DataTable();
+
+    // ...
+```

+<?php
+
+namespace Khill\Lavacharts\Symfony\Bundle\Twig;
+
+use Khill\Lavacharts\Lavacharts;

+     * The Lavacharts object passed in from the service container.
+     *
+     * @var \Khill\Lavacharts\Lavacharts
+     */
+    private $lava;
+

+        $this->lava = $lava;
+    }
+
+    public function getFunctions()
+    {
+        $chartClassesProp = new \ReflectionProperty(Lavacharts::class, 'chartClasses');
+        $chartClassesProp->setAccessible(true);
+        $chartClasses = $chartClassesProp->getValue(new Lavacharts);
+
+        $renderFunctions = [];
+
+        foreach ($chartClasses as $chartClass) {
+            $renderFunctions[] = new \Twig_SimpleFunction(strtolower($chartClass),
+                function($chartLabel, $elemId) use ($chartClass) {
+                    return $this->renderChart($chartClass, $chartLabel, $elemId);
+                }
+            );
+        }
+
+        return $renderFunctions;
+    }
+
+    public function renderChart($chartType, $chartLabel, $elemId)
+    {
+        return $this->lava->render($chartType, $chartLabel, $elemId);
+    }
+
+    public function getName()
+    {
+        return 'lavacharts_twig_extension';
+    }
