+# FrankenPHP Runtime for Symfony
+
+A runtime for [FrankenPHP](https://frankenphp.dev/).
+
+If you are new to the Symfony Runtime component, read more in the [main readme](https://github.com/php-runtime/runtime).
+
+## Installation
+
+```
+composer require runtime/frankenphp-symfony
+```
+
+## Usage
+
+Define the environment variable `APP_RUNTIME` for your application.
+
+```
+// .env
+APP_RUNTIME=Runtime\FrankenPhpSymfony\Runtime
+```
+
+```
+// .rr.yaml
+server:
+    ...
+    env:
+        APP_RUNTIME: Runtime\FrankenPhpSymfony\Runtime
+```
+
+```php
+// public/index.php
+
+use App\Kernel;
+
+require_once dirname(__DIR__).'/vendor/autoload_runtime.php';
+
+return function (array $context) {
+    return new Kernel($context['APP_ENV'], (bool) $context['APP_DEBUG']);
+};
