 This is a [Next.js](https://nextjs.org) project bootstrapped with [`create-next-app`](https://nextjs.org/docs/app/api-reference/cli/create-next-app).
 ## Getting Started
 First, run the development server:
 ```bash
 npm run dev
 # or
 yarn dev
 # or
 pnpm dev
 # or
 bun dev
 ```
 Open [http://localhost:3000](http://localhost:3000) with your browser to see the result.
 You can start editing the page by modifying `app/page.tsx`. The page auto-updates as you edit the file.
 This project uses [`next/font`](https://nextjs.org/docs/app/building-your-application/optimizing/fonts) to automatically optimize and load [Geist](https://vercel.com/font), a new font family for Vercel.
 ## Learn More
 To learn more about Next.js, take a look at the following resources:
 - [Next.js Documentation](https://nextjs.org/docs) - learn about Next.js features and API.
 - [Learn Next.js](https://nextjs.org/learn) - an interactive Next.js tutorial.
 You can check out [the Next.js GitHub repository](https://github.com/vercel/next.js) - your feedback and contributions are welcome!
 ## Deploy on Vercel
 The easiest way to deploy your Next.js app is to use the [Vercel Platform](https://vercel.com/new?utm_medium=default-template&filter=next.js&utm_source=create-next-app&utm_campaign=create-next-app-readme) from the creators of Next.js.
 Check out our [Next.js deployment documentation](https://nextjs.org/docs/app/building-your-application/deploying) for more details.
