-<br>
+### Multi-Module Structure
+
+투유는 확장성과 유지보수성을 위해 멀티모듈 아키텍처를 채택했습니다.
+
+#### Module Dependency Graph
+
+![Project Dependency Graph](docs/project-dependency-graph.png)
+
+#### Module Overview
+
+**:app**
+- 앱의 진입점 및 전체 네비게이션 관리
+- 각 feature 모듈 통합
+
+**:feature modules**
+- `:feature:home` - 홈 화면 및 감정우표 선택
+- `:feature:create` - 일기카드 생성
+- `:feature:social` - 친구 목록 및 질문하기
+- `:feature:record` - 일기카드 기록 확인
+- `:feature:mypage` - 마이페이지 및 프로필 관리
+- `:feature:notice` - 알림 관리
+- `:feature:onboarding` - 로그인 및 회원가입
 
-## PACKAGE STRUCTURE
+**:core modules**
+- `:core:data` - Repository 구현 및 데이터 소스 통합
+- `:core:domain` - 비즈니스 로직 및 모델 정의
+- `:core:network` - API 서비스 및 네트워크 설정
+- `:core:datastore` - 로컬 데이터 저장 (Token, Preferences)
+- `:core:designsystem` - 공통 UI 컴포넌트 및 테마
+- `:core:common` - 공통 유틸리티

+### 의존성 그래프 생성
+
+프로젝트 의존성 그래프를 생성하려면 Graphviz가 필요합니다:
+
+```bash
+# Graphviz 설치 (macOS)
+brew install graphviz
+
+# 의존성 그래프 생성
+./gradlew generateProjectDependencyGraph
+
+# 생성된 파일 위치
+# build/reports/project-dependency-graph/project-dependency-graph.png
+# build/reports/project-dependency-graph/project-dependency-graph.svg
 ```
