 ### The `useScript` composable
 
-Starting from Nuxt 3.11, it is possible to insert any external script in one single line with the new `useScript` composable.
+The Nuxt Scripts module allows you to insert any external script in one single line with its `useScript` composable.
 
 ```ts
 useScript('https://cdn.jsdelivr.net/npm/bootstrap@5.3.2/dist/js/bootstrap.bundle.min.js')

 - It does not insert inline event handlers, therefore CSP will never block the script from executing after load
 - It is designed to load and execute asynchronously, which means you don't have to write code to check whether the script has finished loading before using it
 
-For all of these reasons, we strongly recommend `useScript` as the best way to load your external scripts in a CSP-compatible way.
+In addition, Nuxt Scripts provide easy integration of `useScript` into any Nuxt application:
+- A number of standard scripts are already pre-packaged
+- You can load your scripts globally in `nuxt.config.ts`
+- `useScript` is auto-imported
 
-The `unjs/unhead` repo has a [detailed section here](https://unhead.unjs.io/usage/composables/use-script) on how to use `useScript`.
+For all of these reasons, we strongly recommend using the Nuxt Scripts module as the best way to load your external scripts in a CSP-compatible way.

+Check out their examples on [@nuxt/scripts](https://scripts.nuxt.com) and find out how easy it is to include Google Analytics in your application:
 
 ```ts
-import { useScript } from 'unhead'
-
-const { gtag } = useScript({
-  src: 'https://www.google-analytics.com/analytics.js',
-}, {
+const { gtag } = useScript('https://www.google-analytics.com/analytics.js', {
   use: () => ({ gtag: window.gtag })
 })
 // Now use any feature of Google's gtag() function as you wish
 // Instead of writing complex code to find and check window.gtag
 ```
 
+If you don't want to install the Nuxt Scripts module, you can still use the uderlying native `useScript` method. You will need to `import { useScript } from '@unhead/vue'` in order to use it.
