Add traditional production deployment instructions to readme

    - review and adjust `compose.yaml`

    - run the stack (e.g. `podman compose up -d` or `docker compose up -d`)

- if not, look at `compose.yaml` and `sample.env`

## Production (traditional)

- install [uv](https://docs.astral.sh/uv/) (Debian does not have it in the official repositories, so you can download a tarball from [github](https://github.com/astral-sh/uv/releases) and extract `uv` binary to `/usr/local/bin`)

- install and start redis/valkey (Debian: `apt install valkey-server` and `systemctl start valkey-server && systemctl enable valkey-server`)

- create user, group and homedir: `useradd --system --home-dir /var/www/wybory --shell /sbin/nologin --user-group wybory && mkdir -p /var/www/wybory && chown wybory:wybory /var/www/wybory`

- clone the repo: `git clone <...> /var/www/wybory && cd /var/www/wybory`

- write the config file: `cp sample.env .env` and adjust .env to your needs

- prepare venv: `sudo -u wybory uv sync --locked`

- write service config, e.g. for systemd:

    write `/etc/systemd/system/wybory.service`:

    ```

    After=valkey-server.service network.target

    Requires=valkey-server.service

    ```

    write `/etc/systemd/system/wybory-worker.service`:

    ```

    [Unit]

    After=valkey-server.service network.target

    Requires=valkey-server.service

    [Service]

    WantedBy=multi-user.target

    ```

    `mkdir -p /var/log/wybory` and and do `systemctl daemon-reload` to read the new service file.

    You can adjust gunicorn configuration with command line arguments (see `sudo -u wybory uv run gunicorn --help`),

    or by providing a different config file than `/var/www/wybory/gunicorn.conf.py`.

    It it advised to adjust the number of workers (`--workers <number-of-workers>` or `workers` variable in the config file).

- start and enable the services (for systemd: `systemctl start wybory.service && systemctl enable wybory.service && systemctl start wybory-worker.service && systemctl enable wybory-worker.service`)

- create a superuser `sudo -u wybory uv run python manage.py createsuperuser`

- serve the traffic through a reverse proxy
