+## Nuxt 3 Suppport
+
+Nuxt 3 comes with built-in utilities to support session and authentication. We are working on a new official module. Meanwhile, we recommend: 
+
+- [auth starter template](https://github.com/nuxt/examples/tree/main/auth/local) for Nuxt 3
+- [sidebase nuxt auth](https://sidebase.io/nuxt-auth/getting-started) powered by Auth.js
+
 **🚧 please see [status page](http://auth.nuxtjs.org/status) in documentation.**
