+## Architecture
+

+- **Content DB**: MongoDB (connection string in appsettings.json)
+- **Auth DB**: SQLite + EF Core + Identity
+- **Admin Auth**: Role-based (Admin role)
+- **Views**: Razor + Bootstrap 5 (admin) + custom CSS (public)
+
+## Key Files
+
+- `Program.cs`: Middleware, services, database initialization
+- `Models/DatabaseModels.cs`: MongoDB entity models
+- `Services/MongoDBService.cs`: Generic MongoDB CRUD service
+- `Data/ApplicationDbContext.cs`: EF Core Identity context
+- `Controllers/Admin*.cs`: Admin CRUD controllers ([Authorize(Roles="Admin")])
+- `Controllers/*.cs`: Public controllers (Shop, Portfolio, Blog, About, Contact)

+
+## Running the Project
+
+```powershell
+dotnet build    # Build solution
+dotnet run      # Start on http://localhost:5000
+```
+
+## Admin Access
+
+- URL: http://localhost:5000/admin/login
+- Default: admin@skyartshop.com / Admin123! (configure in appsettings.json)
+
+## Future Development Guidelines
+
+- Use MongoDBService for all MongoDB operations
+- Admin controllers must use [Authorize(Roles="Admin")]
+- Slug generation: lowercase, replace spaces with hyphens
+- TempData["SuccessMessage"] / TempData["ErrorMessage"] for user feedback
+- Image uploads go to wwwroot/uploads/images with GUID filenames
+- All views use Razor syntax; avoid direct HTML files
+
+## Optional Enhancements
+
+- Server-side validation (DataAnnotations)
+- Email service for contact form
+- Shopping cart/checkout
+- SEO meta tags
+- Centralized slug utility service
