+[[getting-started.first-application.code.spring-boot-application]]
+==== The @SpringBootApplication Annotation
+The second class-level annotation is `@SpringBootApplication`.
+This annotation is known as a _meta-annotation_, it combines `@SpringBootConfiguration`, `@EnableAutoConfiguration` and `@ComponentScan`.
+
+Of those, the annotation we're most interested in here is `@EnableAutoConfiguration`.
+`@EnableAutoConfiguration` tells Spring Boot to "`guess`" how you want to configure Spring, based on the jar dependencies that you have added.
 Since `spring-boot-starter-web` added Tomcat and Spring MVC, the auto-configuration assumes that you are developing a web application and sets up Spring accordingly.
