+# Redux Toolkit TypeScript Example
+
+This example shows how to integrate Next.js with [Redux Toolkit](https://redux-toolkit.js.org).
+
+**Redux Toolkit**(also known as "RTK" for short) provides a standardized way to write Redux logic. It includes utilities that help simplify many common use cases, including [store setup](https://redux-toolkit.js.org/api/configureStore), [creating reducers and writing immutable update logic](https://redux-toolkit.js.org/api/createreducer), and even [creating entire "slices" of state at once](https://redux-toolkit.js.org/api/createslice). This example showcases each of these features in conjunction with Next.js.
+
+## Deploy Your Own
+
+Deploy the example using [Vercel](https://vercel.com?utm_source=github&utm_medium=readme&utm_campaign=next-example):
+
+[![Deploy with Vercel](https://vercel.com/button)](https://vercel.com/new/clone?repository-url=https://github.com/vercel/next.js/tree/canary/examples/with-redux&project-name=with-redux&repository-name=with-redux)
+
+## How to Use
+
+Execute [`create-next-app`](https://github.com/vercel/next.js/tree/canary/packages/create-next-app) with [npm](https://docs.npmjs.com/cli/init), [Yarn](https://yarnpkg.com/lang/en/docs/cli/create/), or [pnpm](https://pnpm.io) to bootstrap the example:
+
+```bash
+npx create-next-app --example with-redux with-redux-app
+```
+
+```bash
+yarn create next-app --example with-redux with-redux-app
+```
+
+```bash
+pnpm create next-app --example with-redux with-redux-app
+```
+
+Deploy it to the cloud with [Vercel](https://vercel.com/new?utm_source=github&utm_medium=readme&utm_campaign=next-example) ([Documentation](https://nextjs.org/docs/deployment)).
