# Installation

Install the Python SDK from PyPI:

```bash
pip install babelqueue
```

The base install is the zero-dependency core (codec, contracts and dead-letter
helpers) **plus** the `BabelQueue` runtime with an in-process `memory://`
transport — enough for tests and local development.

## Requirements

- **Python** `>=3.9`
- A running **Redis** or **RabbitMQ** broker (only for the matching transport)

## Broker extras

Real brokers are opt-in via extras, which pull in the standard client for that
transport:

```bash
pip install "babelqueue[redis]"   # redis://  (via redis-py)
pip install "babelqueue[amqp]"    # amqp://   (RabbitMQ, via pika)
```
