+## Creator Plugins Retirement: 20 October 2026
+
+Creator Plugins is being retired from Creator Hub, Creator Works MCP and Project
+Setup. The retirement notice in updated Creator apps links to
+[creatorplugins.store](https://creatorplugins.store/) until **20 October 2026,
+00:00 UTC**. From that time it shows a retired notice without a store link,
+including while offline. New in-app catalogue downloads, Unity-menu installation
+and package imports are disabled in the retirement update.
+
+**Your existing assets and Unity projects are not deleted.** Existing downloads,
+package licences and historical repository files remain their own records.
+This does not retire MCP's scene, prefab, component or Visual Scripting tools.
+See [the retirement details](RETIREMENT.md), including older app versions.

+# Creator Plugins Retirement
+
+The Creator Plugins integration in the Creator apps is ending on **20 October
+2026 at 00:00 UTC**. This refers to the in-app catalogue, not to deleting
+community creations or ending the rest of Creator Hub.
+
+## What Changes
+
+- Updated Creator Hub, Creator Works MCP and Project Setup show a retirement
+  notice instead of the catalogue. New catalogue fetches, package downloads,
+  import requests and installation of the optional Unity catalogue menu are
+  disabled in that update.
+- Before the cutoff, the notice offers
+  [creatorplugins.store](https://creatorplugins.store/).
+- At and after the cutoff, the updated app shows the retired notice without
+  that link. The date check is built into the app, works offline and also applies
+  to a notice that was already open. It uses the computer's current clock.
+
+## What Stays
+
+Existing imported assets, Unity project files, downloaded packages and import
+receipts are not removed by this retirement. Each package retains its own licence.
+MCP's scene, prefab, component and Visual Scripting operations are not retired.
+The repository remains a historical record; published package bytes and links
+are not being rewritten as part of this documentation change.
+
+The store is separate from the retired in-app catalogue. This notice does not
+promise its availability, package compatibility or support.
+
+## Older Versions
+
+Install the Creator app update containing the retirement notice to get this
+behaviour. The change cannot remotely rewrite older app binaries or an existing
+Unity catalogue window that has not been updated. Historical import and
+catalogue instructions in this repository describe the older integration and
+are not a promise of continued app support.
+
+## Problems With Existing Assets
+
+Keep a backup before changing a Unity project. Report the exact package, Unity
+and SDK versions, the action attempted, the actual result and relevant errors
+to its maintainer. Remove credentials and private project information before
+sharing logs. Existing licences and maintainer support terms still apply.
