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).
|
||||||
|
|
||||||
|
## Getting Started
|
||||||
|
|
||||||
|
First, run the development server:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
npm run dev
|
||||||
|
# or
|
||||||
|
yarn dev
|
||||||
|
# or
|
||||||
|
pnpm 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/basic-features/font-optimization) to automatically optimize and load Inter, a custom Google Font.
|
||||||
|
|
||||||
|
## 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/deployment) for more details.
