The page auto-updates as you edit the file. 20 | 21 | This project uses [`next/font`](https://nextjs.org/docs/basic-features/font-optimization) to automatically optimize and load Inter, a custom Google Font. 22 | 23 | ## Learn More 24 | 25 | To learn more about Next.js, take a look at the following resources: 26 | 27 | - [Next.js Documentation](https://nextjs.org/docs) - learn about Next.js features and API. 28 | - [Learn Next.js](https://nextjs.org/learn) - an interactive Next.js tutorial. 29 | 30 | You can check out [the Next.js GitHub repository](https://github.com/vercel/next.js/) - your feedback and contributions are welcome!
