First, rename the `.env.example` file to `.env` and the `docker-compose.yml.example` to `docker-compose.yml`. Then fill in the values in the `.env` file. The `docker-compose.yml` file should be fine as it is, but you can change the ports and volume locations if you want to.
To build the app, compile the docker container.
```bash
docker compose build
```
To start it you then just have to set up the `docker-compose.yml` and environment variables and use `docker compose up`.
