 # CRUD Approve Plugin
 
+:::danger Not officially supported
+
+This plugin is not officially supported and is not part of the AdminForth plugin lineup.
+For approvals, implement your own logic: hold the change in a resource of your own with
+`beforeSave` / `beforeDelete` hooks, and apply it once a reviewer allows it.
+
+The page below is kept only as a reference for projects that already installed the package.
+It receives no support, no fixes and no compatibility guarantees.
+
+:::

 The CRUD Approve plugin adds a manual approval step for changes made from the AdminForth back-office. Instead of applying `create`, `edit`, or `delete` operations immediately, selected resources can send these operations to an approval queue. A reviewer can then inspect the JSON diff and either approve or reject the pending change.
 
 This is useful when several administrators can modify important records, but final responsibility for applying changes should stay with a smaller group of trusted users.
