To allow teams to read a code-based wiki in Azure DevOps, you need to ensure that the team members have the appropriate permissions. By default, all members of the Contributors group can read and edit wiki pages. However, if you are having permission issues, you may need to adjust the permissions.
To manage the wiki repository permissions, you can grant or restrict access for reading and editing wiki pages. You can open the Security dialog by selecting More actions > Wiki security. If you don't have access to create a wiki page, contact an Administrator, who can grant you adequate permission on the underlying Git repository of the wiki.
Additionally, anyone who is a member of the Contributors security group can add or edit wiki pages. Any user with access to the team project, including stakeholders, can view the wiki.
Please ensure that the team members have at least Basic access to create and modify a wiki. They must also have the permission Create Repository to publish code as wiki. By default, this permission is set for members of the Project Administrators group.
