 - `@Configuration` tags the class as a source of bean definitions for the application context.
 - `@EnableAutoConfiguration` tells Spring Boot to start adding beans based on classpath settings, other beans, and various property settings.
-- `@EnableWebMvc` signals Spring MVC that this application is a web application and to activate key behaviors such as setting up a `DispatcherServlet`.
+- Normally you would add `@EnableWebMvc` for a Spring MVC app, but Spring Boot adds it automatically when it sees **spring-webmvc** on the classpath. This flags the application as a web application and activates key behaviors such as setting up a `DispatcherServlet`.
 - `@ComponentScanning` tells Spring to look for other components, configurations, and services in the the `hello` package, allowing it to find the `HelloController`.
 
 The `main()` method uses Spring Boot's `SpringApplication.run()` method to launch an application. Did you notice that there wasn't a single line of XML? No **web.xml** file either. This web application is 100% pure Java and you didn't have to deal with configuring any plumbing or infrastructure.
