 1 | This is a [Next.js](https://nextjs.org/) project bootstrapped with [`create-next-app`](https://github.com/vercel/next.js/tree/canary/packages/create-next-app).
 2 | 
 3 | ## Getting Started
 4 | 
 5 | First, run the development server:
 6 | 
 7 | ```bash
 8 | npm run dev
 9 | # or
10 | yarn dev
11 | ```
12 | 
13 | Open [http://localhost:3000](http://localhost:3000) with your browser to see the result.
14 | 
15 | You can start editing the page by modifying `pages/index.tsx`. The page auto-updates as you edit the file.
16 | 
17 | [API routes](https://nextjs.org/docs/api-routes/introduction) can be accessed on [http://localhost:3000/api/hello](http://localhost:3000/api/hello). This endpoint can be edited in `pages/api/hello.ts`.
18 | 
19 | The `pages/api` directory is mapped to `/api/*`. Files in this directory are treated as [API routes](https://nextjs.org/docs/api-routes/introduction) instead of React pages.
20 | 
21 | ## Learn More
22 | 
23 | To learn more about Next.js, take a look at the following resources:
24 | 
25 | - [Next.js Documentation](https://nextjs.org/docs) - learn about Next.js features and API.
26 | - [Learn Next.js](https://nextjs.org/learn) - an interactive Next.js tutorial.
27 | 
28 | You can check out [the Next.js GitHub repository](https://github.com/vercel/next.js/) - your feedback and contributions are welcome!
29 | 
30 | ## Deploy on Vercel
31 | 
32 | 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.
33 | 
34 | Check out our [Next.js deployment documentation](https://nextjs.org/docs/deployment) for more details.
