 === Change the Location of External Properties of an Application
 By default, properties from different sources are added to the Spring `Environment` in a defined order (see "`<<spring-boot-features.adoc#boot-features-external-config>>`" in the '`Spring Boot features`' section for the exact order).
 
-A nice way to augment and modify this ordering is to add `@PropertySource` annotations to your application sources.
-Classes passed to the `SpringApplication` static convenience methods and those added using `setSources()` are inspected to see if they have `@PropertySources`.
-If they do, those properties are added to the `Environment` early enough to be used in all phases of the `ApplicationContext` lifecycle.
-Properties added in this way have lower priority than any added by using the default locations (such as `application.properties`), system properties, environment variables, or the command line.
-
 You can also provide the following System properties (or environment variables) to change the behavior:
 
 * configprop:spring.config.name[] (configprop:spring.config.name[format=envvar]): Defaults to `application` as the root of the file name.
