 When the `@ConfigurationProperties` bean is registered using configuration property scanning or through `@EnableConfigurationProperties`, the bean has a conventional name: `<prefix>-<fqn>`, where `<prefix>` is the environment key prefix specified in the `@ConfigurationProperties` annotation and `<fqn>` is the fully qualified name of the bean.
 If the annotation does not provide any prefix, only the fully qualified name of the bean is used.
 
-The bean name in the example above is `some.properties-com.example.app.SomeProperties`.
+Assuming that it is in the `com.example.app` package, the bean name of the `SomeProperties` example above is `some.properties-com.example.app.SomeProperties`.
 ====
 
 We recommend that `@ConfigurationProperties` only deal with the environment and, in particular, does not inject other beans from the context.
