Versioning an API - docs?

I’m trying to learn how to create API versions from Stoplight Studio online, but can’t find documentation on the subject.

The only relevant reference I find on the community forum is this one, which points to this page, which looks like a different screen from what I’m seeing.

Help?

Bump.

I have the same question. It seems I can directly edit an API version in studio, but whenever I look at the same API in docs, it has a “not versioned” button. Also, the page referenced in https://docs.stoplight.io/platform/versioning/versions doesn’t seem to exist in the current interface.
