Execute [`create-next-app`](https://github.com/segmentio/create-next-app) with [Yarn](https://yarnpkg.com/lang/en/docs/cli/create/) or [npx](https://github.com/zkat/npx#readme) to bootstrap the example:
You will need a _Sentry DSN_ for your project. You can get it from the Settings of your Project, in **Client Keys (DSN)**, and copy the string labeled **DSN (Public)**.
The Sentry DSN should then be added as an environment variable when running the `dev`, `build`, and `start` scripts in `package.json`:
_Note: Setting environment variables in a `package.json` is not secure, it is done here only for demo purposes. See the [`with-dotenv`](../with-dotenv) example for an example of how to set environment variables safely._
