+Configuration
+=============
+
+Minimal client configuration
+----------------------------
+
+Configure your first client in your config file:
+
+.. code-block:: yaml
+
+    # app/config/config.yml
+    be_simple_soap:
+        clients:
+            DemoApi:
+                wsdl: http://localhost:8086/app_dev.php/ws/DemoApi?wsdl
+
+
+Using client
+------------
+
+.. code-block:: php
+
+    namespace Acme\DemoBundle\Controller;
+
+    use Symfony\Bundle\FrameworkBundle\Controller\Controller;
+
+    class DemoController extends Controller
+    {
+        public function helloAction($name)
+        {
+            // The client service name is `besimple.soap.client.demoapi`:
+            // `besimple.soap.client.`: is the base name of your client
+            // `demoapi`: is the name specified in your config file converted to lowercase
+            $client = $this->container->get('besimple.soap.client.demoapi');
+
+            // call `hello` method on WebService with the string parameter `$name`
+            $helloResult = $client->hello($name);
+
+            return $this->render('AcmeDemoBundle:Demo:hello.html.twig', array(
+                'hello' => $helloResult,
+            ));
+        }
+    }

+Configuration
+~~~~~~~~~~~~~
+
+.. code-block:: yaml
+
+    # app/config/config.yml
+    be_simple_soap:
+        clients:
+            DemoApi:
+                # ...
+                classmap:
+                    User: Acme\DemoBundle\Api\UserApi
+                    # add other type_name: classname
+
+UserApi class
+~~~~~~~~~~~~~
+
+.. code-block:: php
+
+    namespace Acme\DemoBundle\Api;
+
+    class UserApi
+    {
+        private $username;
+
+        private $firstname;
+
+        private $lastname;
+
+        public function __construct($username)
+        {
+            $this->username = $username;
+        }
+
+        public function getFirstname()
+        {
+            return $this->firstname;
+        }
+
+        public function getLastname()
+        {
+            return $this->lastname;
+        }
+    }
+
+Usage
+~~~~~
+
+.. code-block:: php
+
+    namespace Acme\DemoBundle\Controller;
+
+    use Acme\DemoBundle\Api\UserApi;
+    use Symfony\Bundle\FrameworkBundle\Controller\Controller;
+
+    class DemoController extends Controller
+    {
+        public function userAction($username)
+        {
+            // The client service name is `besimple.soap.client.demoapi`:
+            // `besimple.soap.client.`: is the base name of your client
+            // `demoapi`: is the name specified in your config file converted to lowercase
+            $client = $this->container->get('besimple.soap.client.demoapi');
+
+            // call `getUser` method on WebService with an instance of UserApi
+            // if the `getUserByUsername` method return a `User` type then `$userResult` is an instance of UserApi
+            $userResult = $client->getUserByUsername($username);
+
+            return $this->render('AcmeDemoBundle:Demo:user.html.twig', array(
+                'user' => $userResult,
+            ));
+        }
+    }
+
+Without classmap configuration the `$userResult` is an instance of `stdClass`:
+
+.. code-block:: text
+
+    object(stdClass)#5561 (3) {
+      ["username"]=>
+      string(6) "FooBar"
+      ["firstname"]=>
+      string(3) "Foo"
+      ["lastname"]=>
+      string(3) "Bar"
+    }
+
+With classmap configuration the `$userResult` is an instance of `Acme\DemoBundle\Api\UserApi`:
+
+.. code-block:: text
+
+    object(Acme\DemoBundle\Api\UserApi)#208 (3) {
+      ["username":"Acme\DemoBundle\Api\UserApi":private]=>
+      string(6) "FooBar"
+      ["firstname":"Acme\DemoBundle\Api\UserApi":private]=>
+      string(3) "Foo"
+      ["lastname":"Acme\DemoBundle\Api\UserApi":private]=>
+      string(3) "Bar"
+    }
