+## Extensions
+
+`phpunit-json-assertions` provides extensions for simpler handling in different use cases.
+
+### Symfony HttpFoundation Component
+
+The extension `EnricoStahn\JsonAssert\Extension\Symfony` allows to pass in the actual response object generated
+by the symfony framework and takes care of the decoding part.
+
+BEFORE:
+```php
+use EnricoStahn\JsonAssert\Assert as JsonAssert;
+
+// ...
+
+$content = $response->getContent();
+$json = json_decode($content);
+JsonAssert::assertJsonMatchesSchemaString('./my-schema.json', $json);
+```
+
+AFTER:
+```php
+use EnricoStahn\JsonAssert\Assert\Extension\Symfony as JsonAssert;
+
+// ...
+
+JsonAssert::assertJsonMatchesSchemaString('./my-schema.json', $response);
+```
+
 ## Tests
 
 To run the test suite, you need [composer](http://getcomposer.org).
