This section details a number of yaml property files that can be optionally activated as Spring profiles to modify the behavior of Atoti Sign-Off. These files all follow the naming pattern `application-.yaml` to conform with Spring requirements. Each profile sets specific properties to make Atoti Sign-Off work for a particular use case, for example connecting to [Atoti Market Risk](/solutions/market-risk). Specify different profiles by adding the `spring.profiles.active` property in [**application.yaml**](./property-files/application-yml) or by overriding this property at runtime. This section describes the format and values of the profiles provided in Atoti Sign-Off. * [application-mr.yaml](./profiles/application-mr-yaml)
