+<a id="시작하기"></a>
+
+## 🚀 시작하기
+
+### 사전 요구사항
+
+- **Java** 21 이상
+- **Gradle** 8 이상
+- **MySQL** 8 이상
+- **RabbitMQ** 3 이상
+- Firebase 프로젝트 생성 및 서비스 계정 JSON 발급
+
+### 설치
+
+```bash
+# 의존성 설치 및 빌드
+./gradlew build -x test
+```
+
+---
+
+<a id="환경-변수"></a>
+
+## 🔐 환경 변수
+
+`application.yaml`에서 참조하는 환경 변수 목록입니다.
+
+```text
+# ─── Database ───────────────────────────────────────────
+DB_URL=jdbc:mysql://localhost:3306/flipnote_notification
+DB_USERNAME=
+DB_PASSWORD=
+
+# ─── JPA ────────────────────────────────────────────────
+# create | create-drop | update | validate | none
+JPA_DDL_AUTO=validate
+
+# ─── RabbitMQ ───────────────────────────────────────────
+RABBITMQ_HOST=localhost
+RABBITMQ_PORT=5672
+RABBITMQ_USERNAME=guest
+RABBITMQ_PASSWORD=guest
+
+# ─── Firebase ───────────────────────────────────────────
+# 서비스 계정 JSON 전체 내용 (문자열)
+FIREBASE_SERVICE_ACCOUNT_JSON=
+
+# ─── Server ─────────────────────────────────────────────
+SERVER_PORT=8086
+
+# ─── Async Thread Pool ──────────────────────────────────
+ASYNC_CORE_POOL_SIZE=4
+ASYNC_MAX_POOL_SIZE=10
+ASYNC_QUEUE_CAPACITY=100
+
+# ─── Swagger ────────────────────────────────────────────
+SPRINGDOC_SERVER_URL=http://localhost:8086
+```
+
+> **⚠️ 주의**: 환경 변수 파일은 절대 git에 커밋하지 마세요. `.gitignore`에 포함되어 있는지 반드시 확인하세요.
+
+---
+
+<a id="실행-및-배포"></a>
+
+## 🖥️ 실행 및 배포
+
+### 로컬 개발 서버 실행
+
+```bash
+./gradlew bootRun
+```
+
+기본적으로 `http://localhost:8086`에서 실행됩니다.
+Swagger UI는 `http://localhost:8086/notifications/swagger-ui.html`에서 확인할 수 있습니다.
+
+### 프로덕션 빌드
+
+```bash
+./gradlew bootJar
+```
+
+`build/libs/notification-0.0.1-SNAPSHOT.jar` 파일이 생성됩니다.
+
+### 테스트 실행
+
+```bash
+./gradlew test
+```
+
+### Docker 이미지 빌드 및 실행
+
+```bash
+# 이미지 빌드
+docker build -t flipnote-notification .
+
+# 컨테이너 실행
+docker run -p 8086:8086 \
+  -e DB_URL=... \
+  -e FIREBASE_SERVICE_ACCOUNT_JSON=... \
+  flipnote-notification
+```
+
+### 배포 (GitHub Actions)
+
+`main` 브랜치에 push 시 GitHub Actions가 자동으로 아래 과정을 실행합니다.
+
+**CI** (`push` / `pull_request` → `main`)
+1. JDK 21 설치
+2. `./gradlew build -x test` — 빌드 검증
+3. `./gradlew test` — 테스트 실행
+4. Dependency-Check — 취약점 분석 리포트 생성
+
+**CD** (`push` → `main`)
+1. GitHub Container Registry(GHCR) 로그인
+2. Docker 이미지 빌드
+3. `ghcr.io/dungbik/flipnote-notification` 이미지 Push
+
+> 배포에 필요한 시크릿(`ORG_PAT`)은 GitHub Repository → Settings → Secrets and variables → Actions에 등록해야 합니다.
