+**Nâng cấp thêm các tag: Thời gian, Trạng thái và Custom**
 
-## 3. Tech Stack
-The application is built with a focus on performance, security, and clean code principles, strictly following the **Feature-Based MVVM** architecture:
-* **Frontend:** Flutter
-* **Backend & Database:** Supabase (PostgreSQL, Auth, Row Level Security)
-* **Code Quality & CI/CD:** GitHub Actions, SonarCloud
+- **Thời gian & Trạng thái:** Chỉnh sửa sau khi tạo task tại màn hình `task_detail_screen.dart`.
+- **Tag Custom:** - Tối đa 12 ký tự/tag.
+  - Tối đa 5 tags/nhiệm vụ.
+  - Các tag đã tạo sẽ được lưu nội bộ trên máy để dùng lại cho lần sau mà không cần nhập lại.
 
-## 4. Documentation
-For a deeper dive into our system design and development workflows, please explore the attached documentation:
-* [Flutter App Architecture](documentation/architecture/flutter-architecture.md)
-* [Database Schema & ERD](documentation/architecture/database-schema.md)
-* [Git & Conventional Commits Guidelines](documentation/guidelines/conventional-commit.md)
+**⚠️ Lưu ý cài đặt:**
+Để sử dụng tính năng lưu tag custom, **phải thêm** package `shared_preferences`.
