 [Apache Dubbo](https://github.com/apache/dubbo) Spring Boot Project makes it easy to create [Spring Boot](https://github.com/spring-projects/spring-boot/) application using Dubbo as RPC Framework. What's more, it also provides:
-
 * [auto-configure features](dubbo-spring-boot-autoconfigure) (e.g., annotation-driven, auto configuration, externalized configuration).
 * [production-ready features](dubbo-spring-boot-actuator) (e.g., security, health checks, externalized configuration).
