@jeffgbutler Could you please help me add some css styles? :)

@awxiaoxian2020 I think the basic infrastructure is now setup correctly. Do you plan to make additional commits to this PR as you translate the pages, or will you make additional PRs as you make progress?

Yes,I will add more translations about the docs. I don't think it's urgent to launch the Chinese version. So let it be draft for the time being. I will translate the docs when I'm avalible. :)
Thanks for your help!

No activity on this PR for quite some time. Translation of the docs is a huge task. Feel free to reopen if you want to get back to it.
