This provider is already added to the default apps. If you want to add a new app, make sure you add it to your root layout along with [fonts](/packages/design-system/typography) and global CSS, like so: ```tsx layout.tsx theme={"system"} import '@repo/design-system/styles/globals.css'; import { fonts } from '@repo/design-system/lib/fonts'; import { DesignSystemProvider } from '@repo/design-system'; import type { ReactNode } from 'react'; type RootLayoutProperties = { readonly children: ReactNode; }; const RootLayout = ({ children }: RootLayoutProperties) => ( {children} ); export default RootLayout; ```
