 It is also possible to provide your own `EnvironmentRepository` bean
 to be included as part of a composite environment in addition to
 using one of the environment repositories from Spring Cloud.  To do this your bean
-must implement `OrderedEnvironmentRepository`.  For convenience sake, there is
-an abstract implementation of this interface you can extend called
-`AbstractOrderedEnvironmentRepository`.  If you extend `AbstractOrderedEnvironmentRepository`
-your environment repository will have the lowest possible precedence by default.
-If you would like to change this, make sure you call the `setOrder` method
-to set the precedence or override the `getOrder` method to return the order
-value you would like your environment repository to have.
+must implement both the `EnvironmentRepository` and `Ordered` interfaces.
