 Installation
 ============
 
 ### Step 1: Download the GregwarCaptchaBundle
 
-Ultimately, the GregwarCaptchaBundle files should be downloaded to the
-'vendor/bundles/Gregwar/CaptchaBundle' directory.
-
-You can accomplish this several ways, depending on your personal preference.
-The first method is the standard Symfony method.
-
-***Using Composer***
-
-Use composer require to download and install the package.
+Use composer require to download and install the package. 
+At the end of the installation you can automaticly create the configuration thanks to the Symfony recipe.
 
 ``` bash
     composer require gregwar/captcha-bundle
 ```
 
-***Using the vendors script***
-
-Add the following lines to your `deps` file:
-
-```
-    [GregwarCaptchaBundle]
-        git=http://github.com/Gregwar/CaptchaBundle.git
-        target=/bundles/Gregwar/CaptchaBundle
-        version=origin/2.0 <- add this if you are using Symfony 2.0
-```
-
-Now, run the vendors script to download the bundle:
-
-``` bash
-$ php bin/vendors install
-```
-
-***Using submodules***
-
-If you prefer instead to use git submodules, then run the following:
-
-``` bash
-$ git submodule add git://github.com/Gregwar/CaptchaBundle.git vendor/bundles/Gregwar/CaptchaBundle
-$ git submodule update --init
-```
-
-### Step 2: Configure the Autoloader
-
-If you use composer, you can skip this step.
-
-Now you will need to add the `Gregwar` namespace to your autoloader:
-
-``` php
-<?php
-// app/autoload.php
-
-$loader->registerNamespaces(array(
-    // ...
-    'Gregwar' => __DIR__.'/../vendor/bundles',
-));
-```
-### Step 3: Enable the bundle
-
-Finally, enable the bundle in the kernel:
-
-```php
-<?php
-// app/appKernel.php
-
-public function registerBundles()
-{
-    $bundles = array(
-        // ...
-        new Gregwar\CaptchaBundle\GregwarCaptchaBundle(),
-    );
-}
-```
-
 Configuration
 =============
 
-Add the following configuration to your `app/config/config.yml`:
+If you made the configuration automaticly trough the Symfony recipe, you should have the following config file `/config/packages/gregwar_captcha.yaml` 
 
+Otherwise you can create it manually `/config/packages/gregwar_captcha.yaml` with the following default configuration:
+``` yaml
     gregwar_captcha: ~
+```
 
 Usage
 =====
 
 You can use the "captcha" type in your forms this way:
 
-```php
+``` php
 <?php
     use Gregwar\CaptchaBundle\Type\CaptchaType;
     // ...
     $builder->add('captcha', CaptchaType::class); // That's all !
-    // If you're using php<5.5, you can use instead:
-    $builder->add('captcha', 'Gregwar\CaptchaBundle\Type\CaptchaType');
     // ...
 ```

 As URL
 ============
 To use a URL to generate a captcha image, you must add the bundle's routing configuration to your app/routing.yml file:
-
+``` yaml 
     gregwar_captcha_routing:
         resource: "@GregwarCaptchaBundle/Resources/config/routing/routing.yml"
+```
 
 This will use the bundle's route of "/generate-captcha/{key}" to handle the generation. If this route conflicts with an application route, you can prefix the bundle's routes when you import:
-
+``` yaml 
     gregwar_captcha_routing:
         resource: "@GregwarCaptchaBundle/Resources/config/routing/routing.yml"

 Since the session key is transported in the URL, it's also added in another session array, under the `whitelist_key` key, for security reasons
