Scroll Versions classifies users into one of three permission layers, which result from Confluence space permissions assigned under Space tools > Permissions. Depending on a user's permissions, a space managed by Scroll Versions might display different page content and interface.
Readers are users with only View permissions in a space and can be registered or anonymous. They are considered to be the audience for the content authored in a Scroll Versions space and thus only have access to the public content in a space.
The Scroll Versions Public View and versions made available in Scroll Viewport are considered to be public content.
Authors are users with Add page permissions. They have access to non-public versions, can create and edit pages and have access to the author interface.
Admins are users with space or Confluence admin permissions and can perform any operation in a space managed by Scroll Versions. They have access to Space tools > Scroll Add-ons and can create, publish, or delete versions and variants.
Using Confluence permissions as outlined above is recommended. For some advanced setups that require more granular permissions, Scroll Roles can be defined explicitly. See Scroll Roles to learn more.
