-# Getting Started

-### Reference Documentation
-For further reference, please consider the following sections:
-
-* [Official Apache Maven documentation](https://maven.apache.org/guides/index.html)
-* [Spring Boot Maven Plugin Reference Guide](https://docs.spring.io/spring-boot/3.5.7/maven-plugin)
-* [Create an OCI image](https://docs.spring.io/spring-boot/3.5.7/maven-plugin/build-image.html)
-
-### Maven Parent overrides
-
-Due to Maven's design, elements are inherited from the parent POM to the project POM.
-While most of the inheritance is fine, it also inherits unwanted elements like `<license>` and `<developers>` from the parent.
-To prevent this, the project POM contains empty overrides for these elements.
-If you manually switch to a different parent and actually want the inheritance, you need to remove those overrides.
