Beginner Java Developer Interested in Contributing to Processing4

Hi everyone! :waving_hand:
I’m Vanshika, a college student and Java backend developer. I’m interested in contributing to Processing4 and learning how to get started with open-source development.
I’ve looked through the GitHub repo but would appreciate some guidance on where to begin or which issues are beginner-friendly.
Any suggestions or links to contribution guides would be really helpful. Thank you! :blush:
