 ## Default configuration
 
-In the default configuration [init.js](./config/init.js), the seeding creates data in the mongodb database used by the `backend` service (either [v4](../backend/services/v4/), by default, or [v3](../backend/services/v3/) if specified otherwise by setting `BE_VERSION`).

 For an explanation of how setting `BE_VERSION` changes the environment creation see [here](../../README.md#docker-compose-profiles-and-env-variables-configuration-options).
 
 ## Dependency on `BE_VERSION`
 
-Since [v3](../backend/services/v3/) and [v4](../backend/services/v4/) connect to two different DBs, the [BE_VERSION](./compose.yaml#L9) environment variable controls [which DB](./config/init.js#L1) should be seeded (`dacat` for [v3](../backend/services/v3/) and `dacat-next` for [v4](../backend/services/v4/)).
