This feature was proposed by JH and merged into GitLab via an MR. Shipped with JH GitLab 15.4, it brings support for another product Chinese teams actually use. Nice!
The feature itself is simple: it wires Shimo Docs links into JH GitLab. Since plenty of teams already use Shimo Docs for project documentation, they can use it in place of the Wiki.
Preparing Shimo Docs
If you don’t have a team space in Shimo Docs yet, create one. If you do, just copy the team space URL.
JH GitLab Settings
Go to your group or project, click Settings, then Integrations, and pick Shimo Docs:
Paste the Shimo Docs URL in, click Test, then Save:
Now the project’s original Wiki becomes a Shimo Docs link:
That’s all I’ve found by exploring so far. Seems like, roughly, it just swaps the Wiki link? Looking at the MR code, it does seem that simple: https://gitlab.com/gitlab-org/gitlab/-/merge_requests/95161
