# Installation

```bash
composer require babelqueue/symfony
```

## Requirements

- **PHP** `^8.2`
- **Symfony** `^6.4 | ^7.0` (Messenger)
- A broker Messenger supports — **AMQP/RabbitMQ**, **Redis**, etc.

The adapter pulls in the framework-agnostic core (`babelqueue/php-sdk`)
automatically.

## Enable the bundle

With **Symfony Flex** the bundle is registered for you. Otherwise add it to
`config/bundles.php`:

```php
return [
    // ...
    BabelQueue\Symfony\BabelQueueBundle::class => ['all' => true],
];
```

That registers the Messenger serializer (`babelqueue.messenger.serializer`), the
trace-propagation middleware (`babelqueue.messenger.trace_middleware`) and the URN
message registry into the container.
