+# ⚠️ Deprecation Notice
+
+**AutoRest and its plugins are deprecated and will be retired on July 1, 2026.**
+
+AutoRest is no longer under active development. No new features, language generators, or plugins will be added.
+
+### ✅ Recommended replacement: TypeSpec
+
+The recommended successor to AutoRest is **[TypeSpec](https://typespec.io/)** — a modern, actively developed API description language and code generation platform.
+
+**⚠️ No new linting rule will be accepted**. For azure ecosystem add TypeSpec rules here https://github.com/azure/typespec-azure
