像这里在Meta上的翻译

[Moin]

That feature hasn’t been released yet.

@nat

This is currently an experimental feature, and there are some details on how this all works. I will be announcing this properly on meta soon™

The machine-translated button should be shown above the table of content

It is under development still, so nothing at the moment. Eventually it will show when a topic was translated as a way to switch to the original language.
