## Quick Start with Docker Compose

    ```

3.  **Run with Docker Compose**:

    ```bash
    docker compose up -d

    *Note: This will verify the image usage. If you need to rebuild locally, run `docker compose up -d --build`.*

4.  **Check Logs**:

    ```bash
    docker compose logs -f baikal-sync
    ```

## Building & Publishing the Image

    ```bash
    docker build -t lagortinez/baikal-sync:latest .
    ```

2.  **Push** (requires `docker login`):
    ```bash
    docker push lagortinez/baikal-sync:latest
    ```
