# Config

The Configuration Service loads JSON rules for the current application and composes them into a JSON configuration document that is served back. The Configuration Service considers JSON rules that are defined at application level as well as the project, platform and user level.

```
{
    "config": {
        "remote": {
            "enabled": <boolean>,
            "appKey": "<AppKey>"
        }        
    }
}
```
