Date:   Mon Oct 20 13:31:39 2025 +0900

    🚀 초기 프로젝트 설정 완료
    
    ✨ 기능:
    - 기간제 근로자 작업관리 시스템 기본 구조
    - 한국어 기반 프론트엔드 (로그인, 대시보드, 작업자 관리)
    - Node.js Express 백엔드 API 서버 구조
    - MySQL 데이터베이스 스키마 설계
    - 14000번대 포트 구성으로 충돌 방지
    
    📁 구조:
    - frontend/ : HTML, CSS, JS (Bootstrap 5)
    - backend/ : Node.js, Express, MySQL
    - database/ : 초기화 스크립트
    - docs/ : 문서
    
    🔌 포트:
    - 웹: 14000, API: 14001, DB: 14002, phpMyAdmin: 14003
    
    🎯 다음 단계: 백엔드 API 라우트 구현 및 Docker 설정

+# 기간제 근로자 작업관리 시스템
+
+## 📋 프로젝트 개요
+기간제 근로자의 일일 작업, 에러사항, 요청사항을 효율적으로 관리하는 웹 기반 시스템
+
+## 🎯 주요 기능
+- **인증 시스템**: Admin/User 권한 분리
+- **작업자 관리**: 용접사/배관사 직종별 관리
+- **일일 작업관리**: 당일 작업 기록 및 조회
+- **에러사항 관리**: 간편한 에러 등록 및 추적
+- **요청사항 관리**: 장비/소모품 요청 관리
+
+## 🛠️ 기술 스택
+- **Backend**: Node.js + Express + MySQL
+- **Frontend**: Vanilla JS + Bootstrap 5
+- **Database**: MySQL 8.0
+- **배포**: Docker + Docker Compose
+
+## 🔌 포트 구성 (14000번대)
+| 서비스 | 포트 | 접속 URL | 용도 |
+|--------|------|----------|------|
+| **웹 인터페이스** | `14000` | http://localhost:14000 | 프론트엔드 (HTML/CSS/JS) |
+| **API 서버** | `14001` | http://localhost:14001/api | 백엔드 REST API |
+| **MySQL DB** | `14002` | localhost:14002 | 데이터베이스 연결 |
+| **phpMyAdmin** | `14003` | http://localhost:14003 | DB 관리 웹 도구 |
+
+> **💡 포트 선택 이유**: 14000번대를 사용하여 다른 서비스와의 포트 충돌을 방지
+
