Let's start by adding the bundles in your `composer.json` :


```json
{
    "jms/serializer-bundle": "dev-master",
    "friendsofsymfony/user-bundle": "2.0.*@dev",
    "friendsofsymfony/rest-bundle": "1.4.*@dev",
    "friendsofsymfony/oauth-server-bundle": "1.4.*@dev",
    "nelmio/api-doc-bundle": "2.5.*@dev",
}
```

And in your `app/AppKernel.php` :

```php
$bundles = array(
    // ...
    new JMS\SerializerBundle\JMSSerializerBundle(),
    new FOS\UserBundle\FOSUserBundle(),
    new FOS\RestBundle\FOSRestBundle(),
    new FOS\OAuthServerBundle\FOSOAuthServerBundle(),
    new Nelmio\ApiDocBundle\NelmioApiDocBundle(),
    // ...
);
```

And in your `app/config/config.yml` :

```yml
framework:
    # ...
    translator:      { fallback: "%locale%" }
    # ...

fos_user:
    db_driver: orm
    firewall_name: main
