## Prerequisites

Before you begin, ensure you have met the following requirements:

- Node.js installed on your machine.
- Docker and Docker Compose (if you prefer to use Docker).
- `.env` file (if not using Docker) with the necessary environment variables. You can use .env.exmaple as a reference.
