+# Code Universe
+
+Welcome to **Code Universe**, an interactive, space-themed educational platform designed to make learning programming languages engaging and immersive. By exploring different "Planets" (such as HTML, CSS, JavaScript, etc.), users can traverse through a structured curriculum, complete interactive coding challenges, and level up their skills.
+
+**Live Demo:** [code-universe-nu.vercel.app](https://code-universe-nu.vercel.app)
+
+## Key Features
+
+- **Interactive "Planet" Curriculum:** Step-by-step learning paths represented as explorable planets, each focusing on specific concepts and coding challenges.
+- **Integrated Code Editor:** Write and test code directly in the browser with our built-in Monaco Editor integration, providing a VS Code-like experience.
+- **Drag-and-Drop Activities:** Engaging UI interactions powered by `@dnd-kit` for interactive exercises.
+- **Internationalization (i18n):** Multi-language support (English, Azerbaijani, and more) to make learning accessible globally.
+- **Stunning Animations:** Smooth transitions and micro-interactions powered by **Framer Motion** and **GSAP** for a truly premium feel.
+- **Secure Authentication:** Seamless user login and role management handled by **NextAuth.js**.
+
+## Tech Stack
+
+Code Universe is built using modern, highly scalable web technologies:
+
+### Frontend
+- **Framework:** Next.js (App Router, React 19)
+- **Styling:** Tailwind CSS v4
+- **Animations:** Framer Motion & GSAP
+- **Code Editor:** Monaco Editor
+- **State Management & Data Fetching:** TanStack React Query & Immer
+- **Drag & Drop:** @dnd-kit
+- **Icons:** FontAwesome & Lucide React
+
+### Backend & Database
+- **API:** Next.js Server Actions & Route Handlers
+- **Database ORM:** Prisma
+- **Database:** MongoDB
+- **Authentication:** NextAuth.js (Prisma Adapter)
+- **Cloud Storage:** AWS S3 (via `@aws-sdk/client-s3`)
+
+### Tooling & Code Quality
+- **Language:** TypeScript
+- **Linting & Formatting:** ESLint & Prettier
+- **Analytics:** Vercel Analytics & Speed Insights
+
+## Project Structure
+
+- `src/app` - Next.js App Router (Public and Protected routes, API handlers)
+- `src/components` - Reusable React components (UI elements, layout wrappers)
+- `src/lib` - Utility functions, constants, and shared logic
+- `src/i18n` - Internationalization configuration and dictionaries
+- `prisma` - Database schema and migrations
+- `public` - Static assets like images and favicons
