+## Example app using Google Maps Embed
+
+This example shows how to embed a Google Maps Embed using `@next/third-parties`.
+
+## 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-google-maps-embed&project-name=with-google-maps-embed&repository-name=with-google-maps-embed)
+
+## 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-google-maps-embed with-google-maps-embed-app
+```
+
+```bash
+yarn create next-app --example with-google-maps-embed with-google-maps-embed-app
+```
+
+```bash
+pnpm create next-app --example with-google-maps-embed with-google-maps-embed-app
+```
+
+Next, copy the `.env.local.example` file in this directory to `.env.local` (which will be ignored by Git):
+
+```bash
+cp .env.local.example .env.local
+```
+
+Set the `NEXT_PUBLIC_GOOGLE_API_KEY` variable in `.env.local` to match your Google Maps API Key.
+
+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)).
