+cd Gov-chat-bot
+chmod +x install.sh
+./install.sh
+```
+
+> **Windows 사용자** → [Windows 설치 가이드](docs/WSL2_가이드.md)
+
+### 설치 후 접속
+
+```
+관리자 화면: http://localhost:3000

+```
+
+---
+
+## 📋 시스템 요구사항
+
+| 항목 | 최소 |
+|------|------|
+| OS | Ubuntu 20.04+ / macOS 13+ / Windows 11 (WSL2) |
+| RAM | 4GB |
+| 디스크 | 20GB |

+| 인터넷 | 설치 시 필요 (이후 오프라인 운영 가능) |
+
+---
+
+## 📖 사용 방법
+
+### 1단계 — 관리자 계정 만들기
+
+```bash
+docker compose exec backend python -m app.scripts.create_admin
+```
+
+조직 ID(영문), 이메일, 비밀번호를 입력하면 완료.
+
+### 2단계 — FAQ 등록하기
+
+1. http://localhost:3000 에서 로그인
+2. **FAQ 관리** → **+ FAQ 추가**
+3. 카테고리, 질문, 답변 입력 → 저장
+
+> **팁**: 같은 뜻이지만 표현이 다른 질문을 여러 개 등록할수록 인식률이 높아집니다.
+> - "영업시간이요?" / "몇시에 열어요?" / "오늘 언제까지 해요?" → 같은 답변으로 등록
+
+### 3단계 — 문서 업로드하기 (선택)
+
+자주 묻는 내용이 담긴 PDF, Word 파일을 올리면 AI가 자동으로 학습합니다.
+
+1. **문서 관리** → **+ 문서 업로드**
+2. 파일 선택 (PDF · Word · 텍스트)
+3. 처리 완료 후 **승인** 클릭
+
+### 4단계 — 테스트하기
+
+**시뮬레이터** 메뉴에서 실제 질문을 입력해 답변을 미리 확인할 수 있습니다.
+
+### 5단계 — 홈페이지에 위젯 달기
+
+홈페이지 HTML에 아래 코드를 붙여넣기만 하면 됩니다.
+
+```html
+
+```
+
+---
+
+## ⚙️ 환경 설정
+
+```bash
+# 설정 파일 복사
+cp .env.example .env
+
+# 텍스트 에디터로 열어서 수정
+nano .env # 또는 메모장으로 열기
+```
+
+**반드시 바꿔야 할 항목:**
+
+| 항목 | 설명 |
+|------|------|
+| `SECRET_KEY` | 보안 키 (아무 긴 문자열, 32자 이상) |
+
+**선택 항목 (LLM 연결):**
+
+| 항목 | 설명 |
+|------|------|
+| `LLM_PROVIDER=anthropic` | Claude AI 사용 |
+| `ANTHROPIC_API_KEY=...` | Claude API 키 |
+| `LLM_PROVIDER=openai` | ChatGPT 사용 |
+| `OPENAI_API_KEY=...` | OpenAI API 키 |
+
+> LLM 없이도 FAQ + 문서 기반 답변이 충분히 잘 동작합니다. 처음에는 LLM 없이 시작하세요.
+
+---
+
+## 🏗️ 동작 원리
+
+고객이 질문하면 아래 순서로 가장 적합한 답변을 찾습니다.
+
+```
+고객 질문
+ │
+ ▼
+① FAQ 검색 (등록된 FAQ와 유사도 비교)
+ │ 비슷한 FAQ 있음 → 즉시 답변
+ │ 없음 ↓
+ ▼
+② 문서 검색 (업로드한 파일에서 관련 내용 추출)
+ │ 관련 내용 있음 + LLM 연결됨 → AI가 자연스럽게 재서술
+ │ 관련 내용 있음 + LLM 없음 → 문서 내용 그대로 안내
+ │ 없음 ↓
+ ▼
+③ 담당자 안내 (설정한 연락처로 안내)
+```

+## 🔧 자주 묻는 질문 (설치·운영)
+
+**Q. 클라우드 서버가 있어야 하나요?**
+A. 아니요. 사무실 컴퓨터(윈도우·맥·리눅스)에서 바로 실행됩니다. 외부에서 접속하려면 공인 IP나 클라우드 서버가 필요합니다.
+
+**Q. 카카오톡 계정이 있어야 하나요?**
+A. 카카오톡 연동은 선택 사항입니다. 홈페이지 위젯만으로도 운영할 수 있습니다.
+
+**Q. LLM(Claude·ChatGPT) API 비용이 걱정돼요.**
+A. LLM 연결 없이도 FAQ + 문서 기반 답변이 잘 작동합니다. LLM은 나중에 필요할 때 추가하면 됩니다.
+
+**Q. 고객 대화 내용이 외부로 나가나요?**
+A. LLM을 사용하지 않으면 외부 API 호출이 전혀 없습니다. 모든 데이터가 내 서버 안에만 있습니다.
+
+**Q. 여러 매장을 동시에 운영할 수 있나요?**
+A. 네. 매장마다 별도의 조직 ID를 만들면 데이터가 완전히 분리되어 관리됩니다.
+
+**Q. 문제가 생기면 어떻게 하나요?**
+A. 로그 확인: `docker compose logs backend`
+ [Issues](https://github.com/sinmb79/Gov-chat-bot/issues)에 남겨주시면 도움드립니다.

+
+## 5분 설치 순서
+
+**1. PowerShell(관리자)** 열기 → `wsl --install` 실행 → 컴퓨터 재시작
+
+**2. Ubuntu** 실행 → 사용자 이름·비밀번호 설정
+
+**3. [Docker Desktop](https://www.docker.com/products/docker-desktop/) 설치**
+ - 설치 후: Settings → Resources → WSL Integration → Ubuntu 켜기 → Apply
+
+**4. Ubuntu 터미널에서:**

+
+## 1. 시스템 요구사항
+
+| 항목 | 최소 | 권장 |
+|------|------|------|
+| OS | Ubuntu 20.04 / macOS 13 | Ubuntu 22.04 LTS |
+| CPU | 2코어 | 4코어 이상 |
+| RAM | 4GB | 8GB 이상 |
+| 디스크 | 20GB | 50GB 이상 |
+| Docker | 24.x 이상 | 최신 버전 |
+
+> **Windows 사용자**: [13장 Windows 설치 가이드](#13-windows-설치-가이드)를 먼저 확인하세요.
+
+---
+
+## 2. 설치 방법
+
+### 방법 A — 자동 설치 스크립트 (권장)
+
+```bash
+git clone https://github.com/sinmb79/Gov-chat-bot.git
+cd Gov-chat-bot
+chmod +x install.sh
+./install.sh
+```
+
+스크립트가 자동으로 처리하는 항목:
+- Docker 설치 확인
+- 설정 파일(`.env`) 생성
+- 서비스 빌드 및 시작
+- 데이터베이스 초기화
+
+### 방법 B — 수동 설치
+
+```bash
+cp .env.example .env
+# .env 파일을 편집하여 설정 입력
+
+docker compose up -d
+docker compose exec backend alembic upgrade head
+```
+
+---
+
+## 3. 초기 설정
+
+### 3-1. 관리자 계정 만들기
+
+```bash
+docker compose exec backend python -m app.scripts.create_admin
+```
+
+입력 항목:
+- **조직 ID**: 영문 소문자 (예: `my-cafe`, `city-hall`, `my-shop`)
+- **이메일**: 로그인에 사용할 이메일
+- **비밀번호**: 8자 이상
+
+### 3-2. 조직 기본 정보 설정 (폴백 메시지용)
+
+AI가 답을 못 찾을 때 표시할 안내 메시지를 설정합니다.
+API를 통해 TenantConfig에 다음 값을 등록하세요:
+
+| 키 | 설명 | 예시 |
+|----|------|------|
+| `tenant_name` | 조직 이름 | 맛있는 식당, 동두천시 |
+| `phone_number` | 대표 전화번호 | 031-000-0000 |
+| `fallback_dept` | 문의 담당 (선택) | 고객센터, 민원과 |
+
+---
+
+## 4. 대시보드 사용법
+
+브라우저에서 `http://서버주소:3000` 접속 후 로그인.
+
+| 메뉴 | 설명 |
+|------|------|
+| 📊 대시보드 | 문의 통계, 자동응답률 현황 |
+| ❓ FAQ 관리 | 자주 묻는 질문 등록·수정·삭제 |
+| 📄 문서 관리 | 자료 파일 업로드·승인·삭제 |
+| 📋 문의 이력 | 처리된 문의 조회 (개인정보 마스킹) |
+| 🚫 악성 감지 | 도배·욕설 사용자 관리 |
+| 💬 시뮬레이터 | AI 응답 미리 테스트 |
+
+---
+
+## 5. FAQ 관리
+
+FAQ는 가장 빠르고 정확한 답변 방식입니다. 유사도가 높은 질문이 들어오면 즉시 답변합니다.
+
+### 효과적인 FAQ 작성 방법
+
+**같은 의미를 여러 표현으로 등록**하면 인식률이 크게 올라갑니다.
+
+```
+질문: "영업시간이 어떻게 되나요?"
+질문: "몇 시에 열어요?" ← 별도 FAQ로 추가
+질문: "오늘 언제까지 하나요?" ← 별도 FAQ로 추가
+→ 세 개 모두 같은 답변으로 연결
+```
+
+**답변 작성 팁:**
+- 짧고 명확하게 (200자 이내 권장)
+- 전화번호, 주소 등 실용 정보 포함
+- 줄바꿈으로 읽기 쉽게
+
+### 카테고리 예시
+
+| 업종 | 카테고리 예시 |
+|------|---------------|
+| 음식점 | 메뉴, 예약, 위치, 영업시간 |
+| 쇼핑몰 | 배송, 교환환불, 결제, 회원 |
+| 병원 | 진료, 예약, 보험, 주차 |
+| 지자체 | 민원, 복지, 세금, 교통 |
+| 학원 | 수강, 수업, 환불, 일정 |
+
+---
+
+## 6. 문서 관리 (자료 학습)
+
+PDF, Word 파일을 올리면 AI가 내용을 자동으로 학습하여 질문에 활용합니다.
+
+### 지원 파일 형식
+
+| 형식 | 확장자 |
+|------|--------|
+| PDF | `.pdf` (이미지 스캔 PDF 불가) |
+| Word | `.docx` |
+| 텍스트 | `.txt` |
+| 마크다운 | `.md` |
+
+### 업로드 절차
+
+1. **문서 관리** → **+ 문서 업로드** → 파일 선택
+2. 상태가 `processed`(처리 완료)로 바뀔 때까지 대기
+3. **승인** 버튼 클릭 → AI가 학습 시작
+
+> **승인하지 않으면 학습되지 않습니다.** 반드시 승인 후 시뮬레이터로 테스트하세요.
+
+### 어떤 자료를 올리면 좋을까요?
+
+- 업무 매뉴얼, 안내 책자
+- 상품 설명서, 이용약관
+- 공지사항, 자주 묻는 질문 모음
+- 가격표, 서비스 안내문
+
+---
+
+## 7. 문의 이력 조회
+
+처리된 모든 문의를 조회할 수 있습니다.
+
+- 고객 발화: **개인정보 자동 마스킹** 처리 후 표시
+- 사용자 식별: 해시값만 표시 (원본 저장 안 됨)
+- Tier 필터로 분류별 조회 가능
+
+---
+
+## 8. 악성 감지 · 이용 제한
+
+반복 욕설, 도배 등 악성 사용자를 단계적으로 제한합니다.
+
+| 레벨 | 이름 | 의미 |
+|------|------|------|
+| 0 | 정상 | 제한 없음 |
+| 1 | 경고 | 경고 메시지 표시 |
+| 2 | 제한 | 응답 지연 |
+| 3 | 일시 정지 | 관리자가 해제해야 함 |
+| 4 | 차단 | 관리자만 해제 가능 |
+| 5 | 영구 차단 | — |
+
+---
+
+## 9. 홈페이지 위젯 삽입
+
+홈페이지 HTML에 아래 코드를 ` ` 태그 바로 앞에 붙여넣으세요.
+
+```html
+
+```
+
+| 속성 | 설명 | 예시 |
+|------|------|------|
+| `data-tenant` | 조직 ID | `my-cafe` |
+| `data-api` | 서버 주소 | `https://bot.myshop.com` |
+| `data-title` | 위젯 제목 | `주문 도우미` |
+| `data-color` | 버튼 색상 | `#e53e3e` (빨강) |
+
+---
+
+## 10. LLM 연동 설정
+
+기본값은 LLM 없이 FAQ + 문서 기반 응답만 사용합니다.
+더 자연스러운 답변을 원하면 AI API를 연결할 수 있습니다.
+
+`.env` 파일을 열어 아래 내용을 수정합니다:
+
+**Claude (Anthropic) 사용:**
+```env
+LLM_PROVIDER=anthropic
+ANTHROPIC_API_KEY=sk-ant-api03-...
+```
+
+**ChatGPT (OpenAI) 사용:**
+```env
+LLM_PROVIDER=openai
+OPENAI_API_KEY=sk-...
+```
+
+설정 후 재시작:
+```bash
+docker compose restart backend
+```
+
+> **비용 주의**: LLM API는 질문 수에 따라 요금이 발생합니다.
+> 처음에는 LLM 없이 시작하고, FAQ와 문서를 충분히 등록한 후 연결하세요.
+
+---
+
+## 11. 백업 · 복구
+
+### 데이터베이스 백업
+
+```bash
+# 백업 (날짜 포함 파일명으로 저장)
+docker compose exec db pg_dump -U botuser smartbot > backup_$(date +%Y%m%d).sql
+
+# 복구
+docker compose exec -T db psql -U botuser smartbot < backup_20260101.sql
+```
+
+### 정기 백업 자동화
+
+```bash
+# crontab -e 에 추가 (매일 새벽 2시)

+## 12. 문제 해결
+
+### 서비스가 안 켜질 때
+
+```bash
+docker compose logs backend # 오류 로그 확인
+docker compose logs db # DB 오류 확인
+docker compose restart # 재시작
+```
+
+### 포트 충돌 오류
+
+```bash
+# docker-compose.yml 파일에서 포트 변경
+# "8000:8000" → "8080:8000"
+# "3000:80" → "3001:80"
+```
+
+### 답변이 엉뚱할 때
+
+- **시뮬레이터**에서 테스트하며 FAQ를 추가하거나 수정
+- 문서 내용이 명확한지 확인 (스캔 이미지 PDF는 인식 불가)
+- FAQ에 더 다양한 표현으로 질문을 추가
+
+### AI 모델 로드 실패
+
+처음 실행 시 한국어 AI 모델(약 400MB)이 자동 다운로드됩니다.
+
+```bash
+# 인터넷 연결 확인
+docker compose exec backend curl -I https://huggingface.co
+
+# 모델 캐시 초기화 후 재시작
+docker compose exec backend rm -rf /root/.cache/huggingface
+docker compose restart backend
+```
