+=== Required permissions
+
+Access to *Tags* requires the `Tag Management` {kib} privilege. To add the privilege, open the menu, 
+click *Stack Management*, then click *Roles*.
+
+In addition:
+
+* The `read` privilege allows you to assign tags to the saved objects for which you have write permission.
+* The `write` privilege enables you to create, edit, and delete tags.
+
+
+NOTE: Having the `Tag Management` {kib} privilege is not required to
+view tags assigned on objects the user has `read` access to, or to filter objects by tags
+in {kib} applications or from the navigational search.
