+### 1. 서버 실행
 ```bash
 python3 server/ptc_api_server.py
 ```
-서버는 기본적으로 4000 포트에서 실행됩니다.
+서버는 기본적으로 4000 포트에서 실행되며, API와 프론트엔드(`/PTC/`)를 함께 제공합니다.
 
 ### 2. 프론트엔드 접속
-`PTC/index.html` 파일을 브라우저로 열거나, 로컬 웹 서버(예: 8000 포트)를 통해 접속합니다.
-API 서버 주소는 `index.html` 내의 `API_BASE` 변수에서 설정할 수 있습니다.
+브라우저에서 `http://localhost:4000/PTC/` 로 접속합니다.
+필요하면 `index.html`의 `apiBase` 쿼리 파라미터로 API 주소를 덮어쓸 수 있습니다.
 
 ## 데이터 업데이트
 `db/import_ptc_xlsx.py` 스크립트를 사용하여 엑셀 데이터를 DB로 변환할 수 있습니다. 자세한 내용은 `db/README.md`를 참조하세요.

 사용 파일
-- start_ptc_share.bat : 관리자 권한으로 실행되며, WSL 서버 시작 + portproxy + 방화벽까지 자동 설정
+- start_ptc_share.bat : 공유용 실행 파일. 관리자 권한으로 다시 실행되어 WSL 서버 시작, IP 공유 설정, 방화벽 허용, 공유 주소 복사까지 처리합니다.
+- set_ptc_source.bat : 사용할 PTC 원본 `.xlsx` 파일을 선택하고 저장한 뒤 서버를 다시 시작합니다.
 - stop_ptc_share.bat : 공유 중지
 - check_ptc_share.bat : 현재 공유 상태 확인
 
 사용 순서
-1. start_ptc_share.bat 실행
-2. 브라우저에서 http://172.16.40.36:8000/PTC/ 확인
-3. 안 되면 check_ptc_share.bat 실행
+1. 원본 파일을 바꾸려면 set_ptc_source.bat 실행
+2. start_ptc_share.bat 실행
+3. 같은 PC에서는 `http://localhost:4000/PTC/` 확인
+4. 다른 사람에게는 배치파일이 출력한 `http://내PCIP:4000/PTC/` 주소 전달
+4. 안 되면 check_ptc_share.bat 실행
 
 주의
 - PC가 켜져 있어야 합니다.
 - WSL이 재시작되어 IP가 바뀌면 start_ptc_share.bat 를 다시 실행하세요.
-- 관리자 권한이 필요합니다.
+- 이제 프론트와 API를 모두 4000 포트 하나로 제공합니다.
