+> CONNECT GOOD, VALUE CHAIN
+>
+**CHAIN-G** Android 애플리케이션은 스마트 공급망 관리 시스템의 현장 업무를 지원하는 모바일 도구입니다.  
+공장 및 가맹점 관리자가 스마트폰을 이용해 제품 바코드를 스캔함으로써 실시간으로 재고를 처리하고 판매 내역을 기록할 수 있는 **스캔 중심의 현장 지원 앱**입니다.
+
+<br>

+| :--- | :--- |
+| **Language** | Java |
+| **UI Components** | Google Material Design, XML |
+| **Scanning** | Google ML Kit Barcode Scanning, CameraX |
+| **Networking** | Retrofit2, GSON |

+
+## 🚀 주요 기능
+
+- **실시간 바코드/QR 스캔**: Google ML Kit와 CameraX를 연동하여 빠르고 정확하게 제품/박스 코드를 인식합니다.
+- **재고 입출고 정보 확인**: 스캔한 박스의 정보를 기반으로 상세 입고/출고 품목을 즉시 확인하고 수량을 체크합니다.
+- **판매 등록 관리**: 가맹점에서 상품 판매 시 바코드 스캔을 통해 판매 데이터를 본사 시스템과 즉시 동기화합니다.
+- **역할 기반 인터페이스**: 로그인한 사용자의 권한(공장/가맹점)에 따라 다른 메인 기능 탭과 서비스를 제공합니다.
+
+<br>
+
+## 🖥️ 주요 화면
+- **로그인 및 실시간 바코드/QR 스캔**

+
+<br>
+
+## 👥 팀 협업 규칙
+
+### ⭐ 개발 규칙 및 컨벤션
+
+- **Activity 및 Layout**: 기능별로 명확히 분리하며, 재사용 가능한 커스텀 뷰는 `common` 패키지에서 관리합니다.
+- **API 연동**: Retrofit 인터페이스를 통해 백엔드 API 명세와 일치하도록 데이터 모델을 동기화합니다.
+- **주석 준수**: 복잡한 스캔 로직이나 카메라 프리뷰 관련 코드는 주석을 통해 의도를 명시합니다.
