+Many of the annotations within the Spring Framework and Spring portfolio
+projects make use of the `@AliasFor` annotation for declaring _attribute
+aliases_ and _attribute overrides_. Common examples include `@RequestMapping`,
+`@GetMapping`, and `@PostMapping` from Spring MVC as well as annotations
+such as `@SpringBootApplication` and `@SpringBootTest` from Spring Boot.
 
+The following sections provide code snippets to demonstrate these features.

+Spring itself makes use of this feature in many core Spring annotations.
