 Thank you for your interest in contributing to PlantUML! This guide will help you build the PlantUML project.
 
 PlantUML can be built using either [Gradle](#building-plantuml-with-gradle) or [Ant](#building-plantuml-with-ant-alternative-method). It's recommended to use Gradle as the primary build tool for this project. You will find instructions for both methods, starting with Gradle.

+### PlantUML & Java 8 Compatibility
 
 We understand the ubiquity and prevalence of Java 8 in numerous environments and infrastructures. Thus, **PlantUML remains steadfastly compatible with Java 8**. Despite the version’s age and the availability of newer releases, we recognize that a substantial number of users and enterprises still depend on Java 8. Therefore, you can confidently run PlantUML in environments where Java 8 is installed, ensuring accessibility and functionality for a wide array of users.

+### Unitary Tests & Advanced Java Versions
 
 While PlantUML maintains its compatibility with Java 8, our development and testing environments leverage the capabilities of more recent Java versions. All unitary tests are conducted using a newer Java version, not only to utilize advanced features and optimizations but also to ensure the robustness of PlantUML in more updated systems.

 - **For Contributors/Developers**: If you wish to run unitary tests, a more recent version of Java will be required. This ensures that tests run efficiently and utilize the latest features/optimizations, but it in no way impedes the usage of PlantUML with older Java versions.

+### Your Contribution Matters
 
 Whether you're using an old or a new version of Java, your feedback, contributions, and insights are valuable in enhancing PlantUML. We strive to maintain a balance between adopting new technology and ensuring accessibility for all users, and your experiences aid us in striking this balance effectively.

 Within certain PlantUML releases, we've incorporated an embedded, compiled version of GraphViz specifically tailored for Windows. This initiative was taken to streamline the user experience for our Windows users, eliminating the need for them to undertake separate installations or configurations.
