-### 다비오 변화 탐지 시스템
+# Dabeeo Detection API
 
-## 웹어플리케이션
\ No newline at end of file
+> Dabeeo 변화 탐지 시스템을 위한 백엔드 API 서버
+
+## 📋 프로젝트 소개
+
+**dabeeo-detection-api**는 공간 데이터의 변화를 탐지하고 관리하기 위한 RESTful API 서버입니다.
+JTS(Java Topology Suite)를 활용한 지오메트리 데이터 처리와 PostgreSQL을 통한 공간 데이터 저장을 지원합니다.
+
+## 🛠️ 기술 스택
+
+| Category | Technology |
+|----------|------------|
+| **Language** | Java 21 |
+| **Framework** | Spring Boot 3.5.7 |
+| **Database** | PostgreSQL (with PostGIS) |
+| **ORM** | Spring Data JPA + Hibernate |
+| **Query** | QueryDSL 5.0.0 (Jakarta) |
+| **Geospatial** | JTS (Java Topology Suite) + GeoJSON |
+| **Connection Pool** | HikariCP |
+| **Build Tool** | Gradle 8.x |
+| **Monitoring** | Spring Boot Actuator |
+| **Container** | Docker + Docker Compose |
+| **CI/CD** | Jenkins |
+
+## 🚀 시작하기
+
+### 필수 요구사항
+
+- Java 21 (JDK 21)
+- PostgreSQL 12+ (PostGIS 확장 필요)
+- Gradle 8.x (또는 Gradle Wrapper 사용)
+- Docker & Docker Compose (선택사항)
+
+### 로컬 환경 설정
+
+1. **저장소 클론**
+```
+https://kamco.git.gs.dabeeo.com/MVPTeam/DABEEO-DETECTION-APPLICATION.git
+```
+
+2. **데이터베이스 설정**
+
+PostgreSQL 데이터베이스를 준비하고 `src/main/resources/application-local.yml`을 생성:
+
+```yaml
+spring:
+  config:
+    activate:
+      on-profile: local
+  datasource:
+    url: jdbc:postgresql://localhost:5432/dabeeo_detection_dev
+    username: your_username
+    password: your_password
+```
+
+> **참고**: `application-local.yml`은 `.gitignore`에 포함되어 있어 Git에 커밋되지 않습니다.
+
+3. **빌드 및 실행**
+
+```bash
+# 빌드
+./gradlew build
+
+# 실행 (local 프로파일)
+./gradlew bootRun
+
+# 또는 JAR 파일로 실행
+java -jar build/libs/ROOT.jar
+```
+
+서버가 시작되면 http://localhost:8080 에서 접근 가능합니다.
+
+## ⚙️ 프로파일 설정
+
+애플리케이션은 환경별로 다른 설정을 사용합니다:
+
+| 프로파일 | 환경 | 포트 | 설정 파일 |
+|---------|------|------|-----------|
+| `local` | 로컬 개발 | 8080 | `application.yml` (기본) |
+| `dev` | 개발 서버 | 7100 | `application-dev.yml` |
+| `prod` | 운영 서버 | 8080 | `application-prod.yml` |
+
+### 프로파일 활성화
+
+```bash
+# 개발 환경으로 실행
+./gradlew bootRun --args='--spring.profiles.active=dev'
+
+# JAR 실행 시
+java -jar build/libs/ROOT.jar --spring.profiles.active=dev
+```
+
+## 🧪 테스트
+
+```bash
+# 전체 테스트 실행
+./gradlew test
+
+# 특정 테스트 클래스 실행
+./gradlew test --tests com.kamco.cd.kamcoback.KamcoBackApplicationTests
+
+# 테스트 리포트 확인
+open build/reports/tests/test/index.html
+```
+
+## 📦 빌드
+
+```bash
+# 전체 빌드 (테스트 포함)
+./gradlew clean build
+
+# 테스트 제외 빌드 (CI/CD에서 사용)
+./gradlew clean build -x test
+
+# JAR 파일만 생성
+./gradlew bootJar
+```
+
+빌드된 JAR 파일: `build/libs/ROOT.jar`

+#   Gradle start up script for POSIX generated by Gradle.
+#
+#   Important for running:
+#
+#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+#       noncompliant, but you have some other compliant shell such as ksh or
+#       bash, then to run this script, type that shell name before the whole
+#       command line, like:
+#
+#           ksh Gradle
+#
+#       Busybox and similar reduced shells will NOT work, because this script
+#       requires all of these POSIX shell features:
+#         * functions;
+#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+#         * compound commands having a testable exit status, especially «case»;
+#         * various built-in commands including «command», «set», and «ulimit».
+#
+#   Important for patching:
+#
+#   (2) This script targets any POSIX shell, so it avoids extensions provided
+#       by Bash, Ksh, etc; in particular arrays are avoided.
+#
+#       The "traditional" practice of packing multiple parameters into a
+#       space-separated string is a well documented source of bugs and security
+#       problems, so this is (mostly) avoided, by progressively accumulating
+#       options in "$@", and eventually passing that to Java.
+#
+#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+#       see the in-line comments for details.
+#
+#       There are tweaks for specific operating systems such as AIX, CygWin,
+#       Darwin, MinGW, and NonStop.
+#
+#   (3) This script is generated from the Groovy template
+#       https://github.com/gradle/gradle/blob/2d6327017519d23b96af35865dc997fcb544fb40/platforms/jvm/plugins-application/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
