# Setting user and group permissions

There are 3 levels of authorisation:

- The lowest permission is "***Reader***", who can see the published diagrams but cannot manipulate them. This means that he has no right to approve or reject the publication.
- The "***Approver***" can approve or reject the publication, or later historicize it.
- The "***Owner***" has the highest authority. He can approve, reject and historicize a publication. He can set the section name, comments and section color, and most importantly the section permissions.

- - - - - -

- The user permission "***Owner***" has no restrictions in the section and its subsections.
- User permissions "***Approver***" and "***Reader***" are affected in subsections where they do not have exclusive personal permission and the default permission is set.
- User permissions take precedence over the default permission in that section. Subsections that do not have the default permission set inherit the user permission.

Using the "***View users***" or "***View groups***" button, you can view the rights of this section through users or groups.

The "*Owner, Approver, Reader*" buttons are used to filter by role. For example, if you want to see a list of all approvers, click on the "*Approver*" button.

Adding or removing privileges is changed using a checkbox and after clicking/unclicking, the message successfully added or removed is displayed.
