+### Uri options
+
+You might need to specify some URI options for constructing the `MongoDB\Client`. Read the [reference] for a complete
+explanation of all the available options.
+
+Implement `UriOptionsInterface` and declare the class as a Symfony service.
+
+```php
+namespace App\Services;
+
+use Facile\MongoDbBundle\Services\UriOptions\UriOptionsInterface;
+
+final class MyCustomUriOptionsProvider implements DriverOptionsInterface
+{
+    /** @var string */
+    private $appname;

+    public function __construct(string $appname) {
+        $this->appname = $appname;

+        $clientConfiguration['appname'] =  $this->appname;
+        return $clientConfiguration;

+}
+```
+
+```yaml
+# config/services.yaml
+App\Services\MyCustomUriOptionsProvider:
+  arguments:
+    $appname: 'APPNAME'
+```
+
+Then use its service id as value of `uriOptions` in the bundle configuration.
+
+```yml
+# config/packages/facile_it_mongodb.yaml
+mongo_db_bundle:
+  uriOptions: 'App\Services\MyCustomUriOptionsProvider'
+  # ...
