+The following library allows using `ServerRequestInterface` objects of the [psr/http-message](https://github.com/php-fig/http-message) library as a source for the [cuyz/valinor](https://github.com/cuyz/valinor) library.
+
+## Installation
+
+```bash
+composer require delolmo/valinor-http-message
+```
+
+## Example
+
+```php
+
+use App\DTO\CustomObject;
+use CuyZ\Valinor\Mapper\Source\Source;
+use CuyZ\Valinor\MapperBuilder;
+use DelOlmo\Valinor\Mapping\Source\ServerRequestSource;
+use Psr\Http\Message\ServerRequestInterface;
+
+final class CustomController
+{
+    public function execute(ServerRequestInterface $request)
+    {
+        // Create the Source using the new InputSource
+        $source = Source::iterable(new ServerRequestSource($input));
+
+        // Create the Mapper, using the desired configuration
+        $mapper = new MapperBuilder())
+            ->allowSuperfluousKeys()
+            ->enableFlexibleCasting()
+            ->mapper();
+
+        // Map the source to whatever object makes sense
+        $mapped = $mapper->map(CustomObject::class, $source);
+
+        // Apply whatever business logic makes sense from here
+        // ...
+    }
+}
+```

+## Final notes
+
+- Versioning of `delolmo/valinor-http-message` will always match `cuyz/valinor` versions. Same goes for PHP versions.
+- Although query params and body params should not share the same name in the Request, it should be noted that, from a ServerRequestSource standpoint, query params always take precedence over body params. That is, if there is a query param and a body param sharing the same name, ServerRequestSource will only use the query param's value for mapping purposes.
+- Considering that many query and body params are retrieved as strings or arrays, it is interesting to note that `enableFlexibleCasting` should also be configured in the Mapper. See [Enabling flexible casting](https://valinor.cuyz.io/latest/mapping/type-strictness/#enabling-flexible-casting) for more information.
