-> Important Notice: This feature is not developed or maintained by the Next.js team — it is an experimental API from the React team. It is still in **early stages** and **not recommended for production use**. The implementation is still being iterated on, and its behavior may change in future React releases.
-> Enabling this feature requires understanding the experimental nature of the API. To fully grasp its behavior, refer to the [React pull request](https://github.com/facebook/react/pull/31975) and related discussions.
+> Important Notice: The `<ViewTransition>` Component is already available in React's Canary release channel.
+> `experimental.viewTransition` is only required to enable deeper integration with Next.js features e.g. automatically
+> [adding Transition types](https://react.dev/reference/react/addTransitionType) for navigations. Next.js specific transition types are not implemented yet.
 
 ## Usage
 
-Once enabled, you can import the `ViewTransition` component from React in your application:
+You can import the [`<ViewTransition>` Component](https://react.dev/reference/react/ViewTransition) from React in your application:
 
 ```jsx
-import { unstable_ViewTransition as ViewTransition } from 'react'
+import { ViewTransition } from 'react'
 ```
 
-However, documentation and examples are currently limited, and you will need to refer directly to React’s source code and discussions to understand how this works.
