 # CommunityToolkit.Aspire.Hosting.Bun library
 
+> **⚠️ DEPRECATION NOTICE**  
+> This package is deprecated. Bun support is now available in the core `Aspire.Hosting.JavaScript` package via `AddBunApp(...)`.
+>
+> **Migration Guide:**
+> - Install `Aspire.Hosting.JavaScript` and remove `CommunityToolkit.Aspire.Hosting.Bun`.
+> - Keep your existing `builder.AddBunApp(...)` calls, but use the core package implementation.
+> - If you're using TypeScript AppHost bindings, continue using `builder.addBunApp(...)` from the generated core bindings.
+>
+> This package will be removed in a future release. Please migrate to `Aspire.Hosting.JavaScript`.
