Many thanks for the review. I’d certainly be happy to pass on your feedback to the team regarding an official tutorial in various languages. I can also create a GitHub issue on your behalf if you wish, or you can submit your own using the plugins GitHub repository.
We also have some documentation on the plugin website in relation setting up and using Site Kit. The documentation is in English, however, if you’re using the Chrome browser or a browser extension you can ensure the contents are translated if visiting, which you may already be aware of.
For some features new to Site Kit we also provide a feature tour, in the forum of guided clickable walkthrough, showcasing the feature. These feature tours are translated into various languages by Google, and also open to those who wish to contribute to any translations for their own language, if not already translated.
Please do let me know if you’d like me to create a GitHub issue for you. I will pass on your feedback to the team regardless. Thank you!
