Changing access permissions for wikis
Only repository collaborators can edit a repository's wiki by default, but you can allow anyone with an account on GitHub AE to edit your wiki.
Wikis are available in internal and private repositories with GitHub AE. Wikis are available in public repositories with GitHub Free and GitHub Free for organizations, and in public and private repositories with GitHub Pro, GitHub Team, GitHub Enterprise Cloud and GitHub Enterprise Server.
