 ### Middleware Options
 
+In order to use these options, you will still have to define the middleware inside of the [`definePageMeta` macro](https://nuxt.com/docs/api/utils/define-page-meta#definepagemeta)

 ### Disabling the global middleware locally
 
 To disable the global middleware on a specific page only, you can use the [`definePageMeta` macro](https://nuxt.com/docs/api/utils/define-page-meta#definepagemeta) to turn `auth` off:
