 The bridge provides an interface of a factory called
 :class:`Symfony\\Bridge\\PsrHttpMessage\\HttpMessageFactoryInterface`
 that builds objects implementing PSR-7 interfaces from HttpFoundation objects.
-It also provide a default implementation using Zend Diactoros internally.
 
 The following code snippet explains how to convert a :class:`Symfony\\Component\\HttpFoundation\\Request`
-to a ``Zend\Diactoros\ServerRequest`` class implementing the
+to a ``Nyholm\Psr7\ServerRequest`` class implementing the
 ``Psr\Http\Message\ServerRequestInterface`` interface::

+    use Symfony\Bridge\PsrHttpMessage\Factory\PsrHttpFactory;
     use Symfony\Component\HttpFoundation\Request;
 
     $symfonyRequest = new Request([], [], [], [], [], ['HTTP_HOST' => 'dunglas.fr'], 'Content');
     // The HTTP_HOST server key must be set to avoid an unexpected error
