Use one Wiki for whole project instead of one for each repository

[ITBuddyMail]

Is there any way to use a single Wiki for all repos in a project?

Hi! The wikis are associated to repositories, so it won't be possible to enable one at the project level. What you could do is use the wiki associated to a repo where everybody have access as the 'project' wiki, and disable wikis for the rest of the repos in the project.

Hope that helps!
