First, open a command console, enter your project directory and execute the following command to download the latest version of this bundle (still in beta, for a stable version look here):

composer require nelmio/api-doc-bundle dev-master

Then add the bundle to your kernel:

class AppKernel extends Kernel
{
    public function registerBundles()
    {
        $bundles = [
            // ...

            new Nelmio\ApiDocBundle\NelmioApiDocBundle(),
        ];

        // ...
    }
}

To browse your documentation with Swagger UI, register the following route:

# app/config/routing.yml
app.swagger_ui:
    resource: "@NelmioApiDocBundle/Resources/config/routing/swaggerui.xml"
    prefix:   /api/doc

If you also want to expose it in JSON, register this route:

# app/config/routing.yml
app.swagger:
    path: /api/doc.json
    methods: GET
    defaults: { _controller: nelmio_api_doc.controller.swagger }

What does this bundle?

It generates you a swagger documentation from your symfony app thanks to Describers. Each of these Describers extract infos from various sources. For instance, one extract data from SwaggerPHP annotations, one from your routes, etc.

If you configured the app.swagger_ui route above, you can browse your documentation at http://example.org/api/doc.

Configure the bundle

As you just installed the bundle, you'll likely see routes you don't want in your documentation such as /_profiler/. To fix this, you can filter the routes that are documented by configuring the bundle:

# app/config/config.yml
nelmio_api_doc:
    routes:
        path_patterns: # an array of regexps
            - ^/api

Use the bundle

You can configure globally your documentation in the config (take a look at the Swagger specification to know the fields available):

nelmio_api_doc:
    documentation:
        info:
            title: My App
            description: This is an awesome app!
            version: 1.0.0

To document your routes, you can use annotations in your controllers:

namespace AppBundle\Controller;

use AppBundle\Entity\User;
use AppBundle\Entity\Reward;
use Nelmio\ApiDocBundle\Annotation\Model;
use Swagger\Annotations as SWG;
use Symfony\Component\Routing\Annotation\Route;

class UserController
{
    /*
     * @Route("/api/{user}/rewards", methods={"GET"})
     * @SWG\Response(
     *     response=200,
     *     description="Returns the rewards of an user",
     *     @SWG\Schema(
     *         type="array",
     *         @Model(type=Reward::class, groups={"full"})
     *     )
     * )
     * @SWG\Parameter(
     *     name="order",
     *     in="query",
     *     type="string",
     *     description="The field used to order rewards"
     * )
     * @SWG\Tag(name="rewards")
     */
    public function fetchUserRewardsAction(User $user)
    {
        // ...
    }
}
