+NOTE: The `environment` property of the particular binder can also be used for any Spring Boot property, 
+including this `spring.main.sources` which can be useful for adding additional configurations for the 
+particular binders, e.g. overriding auto-configured beans.
+
+For example;
+[source, yaml]
+----
+environment:
+    spring:
+        main:
+           sources: com.acme.config.MyCustomBinderConfiguration
