Cuando termines tu resolución, después de realizar el fork al repositorio, tú **debes** abrir una solicitud de extracción (PR) a nuestro repositorio. No hay limitaciones para la implementación, puede seguir el paradigma de programación, la modularización y el estilo que creas que es la solución más adecuada.

+### 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/docs/3.3.2/maven-plugin/reference/html/)
+* [Create an OCI image](https://docs.spring.io/spring-boot/docs/3.3.2/maven-plugin/reference/html/#build-image)
+
+### 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 `` and `` 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.

+### 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/docs/3.3.2/maven-plugin/reference/html/)
+* [Create an OCI image](https://docs.spring.io/spring-boot/docs/3.3.2/maven-plugin/reference/html/#build-image)
+
+### 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 `` and `` 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.
