-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).
+# Next.js Template with App Router
 
-## Getting Started
+A comprehensive, production-ready Next.js template featuring modern development tools, strict linting, testing setup, and CI/CD pipeline.
 
-First, run the development server:
+## 🚀 Features
 
-```bash
+- **Next.js 15** with App Router
-npm run dev
+- **TypeScript** with strict configuration
-# or
+- **Tailwind CSS** for styling
-yarn dev
+- **ESLint** with comprehensive rules
-# or
+- **Prettier** for code formatting
-pnpm dev
+- **Husky** for Git hooks
-# or
+- **lint-staged** for pre-commit checks
-bun dev
+- **Jest** and **React Testing Library** for testing
+- **Commitizen** for conventional commits
+- **Gitea Actions** CI/CD pipeline
+

-Open [http://localhost:3000](http://localhost:3000) with your browser to see the result.
+## 🛠️ Getting Started
 
-You can start editing the page by modifying `app/page.tsx`. The page auto-updates as you edit the file.
+### Prerequisites
 
-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.
+- Bun (latest version recommended)
+- Node.js 18.x or higher (for compatibility)
 
-## Learn More
+### Installation
 
-To learn more about Next.js, take a look at the following resources:
+1. **Clone the repository:**
 
-- [Next.js Documentation](https://nextjs.org/docs) - learn about Next.js features and API.
+   ```bash
-- [Learn Next.js](https://nextjs.org/learn) - an interactive Next.js tutorial.
+   git clone <your-repo-url>
+   cd next-template-app-router
+   ```
 
-You can check out [the Next.js GitHub repository](https://github.com/vercel/next.js) - your feedback and contributions are welcome!
+2. **Install dependencies:**
 
-## Deploy on Vercel
+   ```bash
+   bun install
+   ```
 
-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.
+3. **Set up Git hooks:**
 
-Check out our [Next.js deployment documentation](https://nextjs.org/docs/app/building-your-application/deploying) for more details.
+   ```bash
+   bun run prepare
+   ```
+
+4. **Start the development server:**
+   ```bash
+   bun run dev
+   ```
+
+Open [http://localhost:3000](http://localhost:3000) to view the application.
