Execute create-next-app with npm, Yarn, or pnpm to bootstrap the example:
npx create-next-app --example i18n-routing i18n-routing-appyarn create next-app --example i18n-routing i18n-routing-apppnpm create next-app --example i18n-routing i18n-routing-appDeploy it to the cloud with Vercel (Documentation).
