+This example accompanies our [Add chat to a Next.js app with TalkJS](https://talkjs.com/resources/add-chat-to-a-nextjs-app-with-talkjs/) tutorial. It demonstrates how to integrate TalkJS into a Next.js project using our [React SDK](https://talkjs.com/docs/Reference/React_SDK/Installation/).
 
 The React SDK is not able to render components on the server, so we use Next.js's [Client Components](https://nextjs.org/docs/app/building-your-application/rendering/client-components) to render them on the client.
