+### Step 3: Configure the Bundle
+
+Verify that you have the configuration file `config/packages/rapsys_pack.yaml`
+with the following content:
+
+```yaml
+#Services configuration
+services:
+    #Register assets pack package
+    assets.pack_package:
+        class: Rapsys\PackBundle\Asset\PathPackage
+        arguments: [ '/', '@assets.empty_version_strategy', '@assets.context' ]
+    #Register twig pack extension
+    rapsys_pack.twig.pack_extension:
+        class: Rapsys\PackBundle\Twig\PackExtension
+        arguments: [ '@file_locator', '@service_container', '@assets.pack_package' ]
+        tags: [ twig.extension ]
+```
+
+Open a command console, enter your project directory and execute the
+following command to see default bundle configuration:
+
+```console
+$ php bin/console config:dump-reference RapsysPackBundle
+```
+
+Open a command console, enter your project directory and execute the
+following command to see current bundle configuration:
+
+```console
+$ php bin/console debug:config RapsysPackBundle
+```
+
+### Step 4: Use the twig extension in your Template
+
+You can use a template like this to generate your first `rapsys_pack` enabled template:
+
+```twig
+<!DOCTYPE html>
+<html>
+       <head>
+               <meta charset="UTF-8" />
+               <title>{% block title %}Welcome!{% endblock %}</title>
+               {% stylesheet '//fonts.googleapis.com/css?family=Irish+Grover|La+Belle+Aurore' '@NamedBundle/Resources/public/css/{reset,screen}.css' '@Short/css/example.css' %}
+                       <link rel="stylesheet" type="text/css" href="{{ asset_url }}" />
+               {% endstylesheet %}
+       </head>
+       <body>
+               {% block body %}{% endblock %}
+               {% javascript '@Short/js/*.js' %}
+                       <script type="text/javascript" src="{{ asset_url }}"></script>
+               {% endjavascript %}
+       </body>
+</html>
+```
+
+### Step 5: Make sure you have local binary installed
+
+You need to have cpack and jpack scripts from https://git.rapsys.eu/packer/ repository
+set as executable and installed in /usr/local/bin.
+
+To install cpack and jpack required packages open a root console and execute the
+following command:
+
+```console
+# urpmi perl-base perl-CSS-Packer perl-JavaScript-Packer
+```
+
+or stone age distributions:
+
+```console
+# apt-get install libcss-packer-perl libjavascript-packer-perl
+```
+
+or other distributions through cpan:
+
+```console
+# cpan App::cpanminus
+# cpanm CSS::Packer
+# cpanm JavaScript::Packer
+```
+
+### Step 6: Create your own filter
+
+You can create you own mypackfilter class which call a mypack binary:
+
+```php
+<?php
+
+namespace Rapsys\PackBundle\Twig\Filter;
+
+use Rapsys\PackBundle\Twig\Filter\FilterInterface;
+use Twig\Error\Error;
+
+//This class will be defined in the parameter rapsys_pack.filters.(css|img|js).[x].class string
+class MyPackFilter implements FilterInterface {
+       //The constructor arguments ... will be replaced defined in the parameter rapsys_pack.filters.(css|img|js).[x].args array
+       public function __construct($fileName, $line, $bin = 'mypack', ...) {
+               //Set fileName
+               $this->fileName = $fileName;
+
+               //Set line
+               $this->line = $line;
+
+               //Set bin
+               $this->bin = $bin;
+
+               //Check argument presence
+               if (!empty($this->...)) {
+                       //Append argument
+                       if ($this->... == '...') {
+                               $this->bin .= ' ...';
+                       } else {
+                               //Throw an error on ...
+                               throw new Error(sprintf('Got ... for %s: %s', $this->bin, $this->...), $this->line, $this->fileName);
+                       }
+               }
+       }
+
+       //Pass merge of all inputs in content
+       public function process($content) {
+               //Create descriptors
+               $descriptorSpec = array(
+                       0 => array('pipe', 'r'),
+                       1 => array('pipe', 'w'),
+                       2 => array('pipe', 'w')
+               );
+
+               //Open process
+               if (is_resource($proc = proc_open($this->bin, $descriptorSpec, $pipes))) {
+                       //Set stderr as non blocking
+                       stream_set_blocking($pipes[2], 0);
+
+                       //Send content to stdin
+                       fwrite($pipes[0], $content);
+
+                       //Close stdin
+                       fclose($pipes[0]);
+
+                       //Read content from stdout
+                       if ($stdout = stream_get_contents($pipes[1])) {
+                               $content = $stdout;
+                       }
+
+                       //Close stdout
+                       fclose($pipes[1]);
+
+                       //Read content from stderr
+                       if (($stderr = stream_get_contents($pipes[2]))) {
+                               throw new Error(sprintf('Got unexpected strerr for %s: %s', $this->bin, $stderr), $this->line, $this->fileName);
+                       }
+
+                       //Close stderr
+                       fclose($pipes[2]);
+
+                       //Close process
+                       if (($ret = proc_close($proc))) {
+                               throw new Error(sprintf('Got unexpected non zero return code %s: %d', $this->bin, $ret), $this->line, $this->fileName);
+                       }
+               }
+
+               //Return content
+               return $content;
+       }
+}
+```
+
+The class is required to get it's arguments through constructor and have a process method.
