+## Additional configuration
+
+If there is no requirement for the use of a message broker and the s3 integration is addressed exclusively via REST, the following settings can be used to deactivate the spring-cloud-stream-feature in a service which uses the `digiwf-s3-integration-starter`.
+
+A hardcoded solution to disable the default behaviour with exclusion of specific auto-configuration classes on start up can be found down below.
+
+```java
+...
+import org.springframework.cloud.stream.config.BindingServiceConfiguration;
+import org.springframework.cloud.stream.function.FunctionConfiguration;
+...
+
+/**
+ * Application class for starting the micro-service.
+ */
+@SpringBootApplication(
+        ...
+        // Deactivating the Spring Cloud Stream functionality that is activated by default
+        exclude = { BindingServiceConfiguration.class, FunctionConfiguration.class },
+        ...
+)
+```
+
+An alternative to the hard coded solution is to exclude the classes via the following spring property.
+
+```yml
+spring:
+  autoconfigure:
+    exclude:
+      # Deactivating the Spring Cloud Stream functionality that is activated by default
+      - org.springframework.cloud.stream.config.BindingServiceConfiguration
+      - org.springframework.cloud.stream.function.FunctionConfiguration
+```
