+## Follow-up: applying the same pattern to Spring Native
+
+As a follow-up, you can reuse the ideas from this module to extend the `spring-native` example
+with declarative configuration and a Collector running via Docker Compose:
+
+- Start from the `spring-native` module in this repository.
+- delete the `application.properties` file in `spring-native/src/main/resources/`
+- copy `application.yaml` from this module to `spring-native/src/main/resources/`
+- add the settings from `application.properties` back into that `application.yaml`
+- follow the instructions in [spring-native/README.md](../spring-native/README.md) to run with 
+  Docker Compose
+
+```shell
+rm ../spring-native/src/main/resources/application.properties
+cp src/main/resources/application.yaml ../spring-native/src/main/resources/
+echo "spring:
+  datasource:
+    url: jdbc:h2:mem:db
+management:
+  endpoints:
+    web:
+      exposure:
+        include: '*'" >> ../spring-native/src/main/resources/application.yaml
