+
+The PSR-7 Bridge
+================
+
+ The PSR-7 bridge converts :doc:`HttpFoundation `
+ objects from and to objects implementing HTTP message interfaces defined
+ by the `PSR-7`_.
+
+Installation
+------------
+
+You can install the component in 2 different ways:
+
+* :doc:`Install it via Composer ` (``symfony/psr-http-message-bridge`` on `Packagist`_);
+* Use the official Git repository (https://github.com/symfony/psr-http-message-bridge).
+
+The bridge also needs a PSR-7 implementation to allow converting HttpFoundation
+objects to PSR-7 objects. It provides native support for _`Zend Diactoros`_.
+Use Composer (``zendframework/zend-diactoros`` on `Packagist`_) or refers to
+the project documentation to install it.
+
+Usage
+-----
+
+Converting from HttpFoundation Objects to PSR-7
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+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 explain how to convert a :class:`Symfony\\Component\\HttpFoundation\\Request`
+to a Zend Diactoros :class:`Zend\\Diactoros\\ServerRequest` implementing the
+:class:`Psr\\Http\\Message\\ServerRequestInterface` interface::
+
+ use Symfony\Bridge\PsrHttpMessage\Factory\DiactorosFactory;
+ use Symfony\Component\HttpFoundation\Request;
+
+ $symfonyRequest = new Request(array(), array(), array(), array(), array(), array('HTTP_HOST' => 'dunglas.fr'), 'Content');
+ // The HTTP_HOST server key must be set to avoid an unexpected error
+
+ $psr7Factory = new DiactorosFactory();
+ $psrRequest = $psr7Factory->createRequest($symfonyRequest);
+
+And now from a :class:`Symfony\\Component\\HttpFoundation\\Response` to a Zend
+Diactoros :class:`Zend\\Diactoros\\Response` implementing the :class:`Psr\\Http\\Message\\ResponseInterface`
+interface::
+
+ use Symfony\Bridge\PsrHttpMessage\Factory\DiactorosFactory;
+ use Symfony\Component\HttpFoundation\Response;
+
+ $symfonyResponse = new Response('Content');
+
+ $psr7Factory = new DiactorosFactory();
+ $psrResponse = $psr7Factory->createResponse($symfonyResponse);
+
+Converting Objects implementing PSR-7 Interfaces to HttpFoundation
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+On the other hand, the bridge provide a factory interface called
+:class:`Symfony\\Bridge\\PsrHttpMessage\\HttpFoundationFactoryInterface`
+that builds HttpFoundation objects from objects implementing PSR-7 interfaces.
+
+The next snippet explain how to convert an object implementing the :class:`Psr\\Http\\Message\\ServerRequestInterface`
+interface to a :class:`Symfony\\Component\\HttpFoundation\\Request` instance::
+
+ use Symfony\Bridge\PsrHttpMessage\Factory\HttpFoundationFactory;
+
+ // $psrRequest is an instance of Psr\Http\Message\ServerRequestInterface
+
+ $httpFoundationFactory = new HttpFoundationFactory();
+ $symfonyRequest = $httpFoundationFactory->createRequest($psrRequest);
+
+From an object implementing the :class:`Psr\\Http\\Message\\ResponseInterface`
+to a :class:`Symfony\\Component\\HttpFoundation\\Response` instance::
+
+ use Symfony\Bridge\PsrHttpMessage\Factory\HttpFoundationFactory;
+
+ // $psrResponse is an instance of Psr\Http\Message\ResponseInterface
+
+ $httpFoundationFactory = new HttpFoundationFactory();
+ $symfonyResponse = $httpFoundationFactory->createResponse($psrResponse);
