 This folder provides examples to set up the [Dataspace Connector](https://github.com/International-Data-Spaces-Association/DataspaceConnector).
 We distinguish between three categories:
-1. **Full Setup**: The [Dataspace Connector](https://github.com/International-Data-Spaces-Association/DataspaceConnector) is started with all its extensions, i.e. [ConfigurationManager](https://github.com/International-Data-Spaces-Association/IDS-ConfigurationManager), [GUI](https://github.com/International-Data-Spaces-Association/IDS-ConfigurationManager-UI), [Camel](https://github.com/International-Data-Spaces-Association/DSC-Camel-Instance), Postgres DB.

 2. **Provider-Consumer Setup**: Here two [Dataspace Connectors](https://github.com/International-Data-Spaces-Association/DataspaceConnector) are started, so that data can be exchanged between them. (**tbd.**)
-3. **Slim Setup**: In this setup only the [Dataspace Connector](https://github.com/International-Data-Spaces-Association/DataspaceConnector) and Postgresql as database are started, without Camel, ConfigurationManager and GUI.
