@wiige We have recently split the spine-unity documentation page into multiple pages, and improved the documentation in the installation section since we noticed it was not so clearly structured and missing a few things.
I've created a step-by-step guide on what best to change in which order with links to diffs (and commit URLs, which unfortunately reference a private repository and only serve the purpose so that we later know which change was which). I hope that the guide helps keeping the work as minimal as possible, please let me know if anything is unclear or confusing. I've also uploaded the relevant .md files in case that helps (link see the notes txt file below). In general there should not be much to translate (except for additions in the Installation section), mostly moving text around to the right places, and updating cross-references.
It would be great if you could also split and update the Chinese spine-unity page in the same way. Thanks again for all your hard work! 🙇
