The previous how-to accidentally referenced the `@Repository` annotation
and not the Spring Data `Repository` interface.

 === Use Spring Data Repositories
-Spring Data can create implementations of `@Repository` interfaces of various flavors.
-Spring Boot handles all of that for you, as long as those `@Repository` annotations are included in one of the <<using#using.auto-configuration.packages,auto-configuration packages>>, typically the package (or a sub-package) of your main application class that is annotated with `@SpringBootApplication` or `@EnableAutoConfiguration`.

 For many applications, all you need is to put the right Spring Data dependencies on your classpath.
 There is a `spring-boot-starter-data-jpa` for JPA, `spring-boot-starter-data-mongodb` for Mongodb, and various other starters for supported technologies.
 To get started, create some repository interfaces to handle your `@Entity` objects.
 
-Spring Boot determines the location of your `@Repository` definitions by scanning the <<using#using.auto-configuration.packages,auto-configuration packages>>.

 For more control, use the `@Enable…Repositories` annotations from Spring Data.
