+This is a [Next.js](https://nextjs.org/) project bootstrapped with
+[`create-next-app`](https://github.com/vercel/next.js/tree/canary/packages/create-next-app).
+
+## Incremental migration
+
+We have recently released a new version, v11, of our component library and a
+common question we receive is if users can adopt v11 incrementally and the
+answer is yes! If the burden of migrating to v11 is too big to take on all at
+once, but there are features of our latest release you want to take advantage
+of, it is likely that you can pull in just the parts you are wanting to use
+while keeping the rest of your Carbon usage the same.
+
+This example illustrates how v11 and v10 work together.
+
+## Getting Started
+
+First, run `yarn` or `npm install` and then run the development server:
+
+```bash
+npm run dev
+# or
+yarn dev
+```
+
+Open [http://localhost:3000](http://localhost:3000) with your browser to see the
+result.
+
+You can start editing the page by modifying `pages/index.js`. The page
+auto-updates as you edit the file.
+
+[API routes](https://nextjs.org/docs/api-routes/introduction) can be accessed on
+[http://localhost:3000/api/hello](http://localhost:3000/api/hello). This
+endpoint can be edited in `pages/api/hello.js`.
+
+The `pages/api` directory is mapped to `/api/*`. Files in this directory are
+treated as [API routes](https://nextjs.org/docs/api-routes/introduction) instead
+of React pages.
+
+## Sass
+
+First and foremost, if you want to use v11 styles in any capacity, you'll have
+to migrate to use `dart-sass`. `node-sass` has been deprecated and we migrated
+to `dart-sass` in v11. For more information about migrating, visit our docs
+[here](https://github.com/carbon-design-system/carbon/blob/main/docs/migration/v11.md#changing-from-node-sass-to-sass).
+
+## V10 and V11
+
+This example is mainly v10, but it takes advantage of the new Stack component
+from v11 and uses v11's StructuredList component 🎉. StructuredList had a major
+accessibilty revamp in v11 that you might want to use and this examples shows
+you how.

+## Deploy on Vercel
+
+The easiest way to deploy your Next.js app is to use the
+[Vercel Platform](https://vercel.com/new?utm_medium=default-template&filter=next.js&utm_source=create-next-app&utm_campaign=create-next-app-readme)
+from the creators of Next.js.
