-# Example app with polyfills
-
-Next.js supports browsers from IE10 to the latest. It adds polyfills as they need. But Next.js cannot add polyfills for code inside NPM modules. So sometimes, you need to add polyfills by yourself.
-
-This how you can do it easily with Next.js's custom webpack config feature.
-
-## Deploy your own
-
-Deploy the example using [ZEIT Now](https://zeit.co/now):
-
-[![Deploy with ZEIT Now](https://zeit.co/button)](https://zeit.co/new/project?template=https://github.com/zeit/next.js/tree/canary/examples/with-polyfills)
-
-## How to use
-
-### Using `create-next-app`
-
-Execute [`create-next-app`](https://github.com/zeit/next.js/tree/canary/packages/create-next-app) with [npm](https://docs.npmjs.com/cli/init) or [Yarn](https://yarnpkg.com/lang/en/docs/cli/create/) to bootstrap the example:
-
-```bash
-npm init next-app --example with-polyfills with-polyfills-app
-# or
-yarn create next-app --example with-polyfills with-polyfills-app
-```
-
-### Download manually
-
-Download the example:
-
-```bash
-curl https://codeload.github.com/zeit/next.js/tar.gz/master | tar -xz --strip=2 next.js-master/examples/with-polyfills
-cd with-polyfills
-```
-
-Install it and run:
-
-```bash
-npm install
-npm run dev
-# or
-yarn
-yarn dev
-```
-
-Deploy it to the cloud with [ZEIT Now](https://zeit.co/new?filter=next.js&utm_source=github&utm_medium=readme&utm_campaign=next-example) ([Documentation](https://nextjs.org/docs/deployment)).
+This example has been deprecated and removed in favor of Next.js polyfills chunk ([#10212](https://github.com/zeit/next.js/pull/10212)), which does a better work at identifying the required polyfills for non-modern browsers.
