-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).
+# Interview Coach — Frontend
 
-## Getting Started
+Next.js frontend for the Interview Coach platform.
 
-First, run the development server:
+## Setup
 
 ```bash
-npm run dev
-# or
-yarn dev
-# or
-pnpm dev
-# or
-bun dev
+pnpm install
 ```
 
-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
+This also installs the pre-push git hooks (via lefthook). Hooks run ESLint, Prettier, and TypeScript checks before any push reaches GitHub.
 
-To learn more about Next.js, take a look at the following resources:
+## Development
 
-- [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!
+```bash
+pnpm dev
+```
 
-## Deploy on Vercel
+Open [http://localhost:3000](http://localhost:3000) in your browser.
 
-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.
+## Scripts
 
-Check out our [Next.js deployment documentation](https://nextjs.org/docs/app/building-your-application/deploying) for more details.

+| `pnpm build`        | Production build     |
+| `pnpm lint`         | Run ESLint           |
+| `pnpm format`       | Fix formatting       |
+| `pnpm format:check` | Check formatting     |
