     If you want to use all of the Symfony2 Components, then instead of adding
     them one by one:
 
-        .. code-block:: json
+    .. code-block:: json
 
-            {
-                "require": {

-                    "symfony/dom-crawler": "2.3.*",
-                    "symfony/css-selector": "2.3.*"

     you can use:

+    .. code-block:: json
 
-            {
-                "require": {

     This will include the Bundle and Bridge libraries, which you may not
     actually need.
