+ElixirMixBundle
+===================
+
+ElixirMixBundle is a Symfony bundle that integrates [Laravel Mix](https://github.com/JeffreyWay/laravel-mix). 
+The purpose of the bundle is to offer the `mix()` twig function. This is exactly the same `mix()` function from Laravel 
+blade template system.
+
+### Requirements
+
+Before you start installing this bundle you first have to ensure that Node.js and NPM are installed on your machine. 
+
+## Installation
+
+### Step 1: Require the bundle with composer
+
+Open your terminal and run one of the following commands to download the bundle into your vendor directory.
+
+If you have composer installed globally you can run:
+```
+$ composer require iulyanp/elixir-mix-bundle
+```
+Else you can go with:
+```
+$ php composer.phar require iulyanp/elixir-mix-bundle
+```
+
+### Step 2: Register the bundle in your AppKernel class
+
+Register the bundle in the app/AppKernel.php file of your project:
+
+```
+<?php
+/** app/AppKernel.php */
+
+class AppKernel extends Kernel
+{
+    public function registerBundles()
+    {
+        $bundles = array(
+
+            new Iulyanp\ElixirMixBundle\IulyanpElixirMixBundle(),
+        );
+    }
+}
+```
+
+### Step 3: Initialize larave-mix package
+If you already have installed `Node.js`, `npm` you should be all set to run:
+
+```
+$ php bin/console mix:init
+```
+
+A base `package.json` and `webpack.mix.js` file will be generated into your project root directory.
+
+Then run `npm install` to install all the dependencies and [laravel-mix](https://github.com/JeffreyWay/laravel-mix).
+
+### Usage
+Now you can use mix() function to version a file like this:
+```
+<link rel="stylesheet" type="text/css" href="{{ mix('css/app.css') }}" />
+```
+
+### License
