It depends on how you use this. Contributions are always appreciated!
If you make Minecraft datapacks (or for that matter, GitHub Actions, or backend GitHub stuff in general, etc), you can go over to the
GitHub page, fork it, and send us changes there.
If you know a number of different languages, or even just one, you can head over to the
Crowdin page (assuming it works xD) and help us translate!
If you love helping people out, you can help us write documentation. Use the same steps as a developer, but use the gh-pages branch, as this is what powers our
documentation site!
If you just want to use this datapack, you can just give the datapack and resource pack a diamond!
