 = Starters
 
-Spring Boot Starters are a set of convenient dependency descriptors that you can include
-in your application. You get a one-stop-shop for all the Spring and related technology
-that you need without having to hunt through sample code and copy paste loads of
-dependency descriptors. For example, if you want to get started using Spring and
-JPA for database access include the `spring-boot-starter-data-jpa` dependency in
-your project, and you are good to go.
