 You can also set these options for your whole application using the `gregwar_captcha`
 configuration entry in your `config.yml` file:
 ``` yaml 
-    gregwar_captcha:
-        width: 200
-        height: 50
-        length: 6

 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"
+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"
-        prefix: /_gcb
+gregwar_captcha_routing:
+    resource: "@GregwarCaptchaBundle/Resources/config/routing/routing.yml"
+    prefix: /_gcb
 ```
 
 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
