The default configuration mode may be configured by using a `config.json` or `config.yml` file in the data project root. If a `.env` file is present along with this config file, then it will be loaded, and the environment variables defined therein will be available for token replacements in your configuration document using `${ENV_VAR}` syntax.

For example:

```
# .env
API_KEY=some_api_key

# config.json
{
    "llm": {
        "api_key": "${API_KEY}"
    }
}
```
