-# 10th_Android
-
-
-팀원 구성
-
-
-### Git 작업 순서
-
-본인의 브랜치에서만 작업하고, `main` 브랜치는 직접 수정하지 않습니다.
-
-#### 1. 현재 브랜치 확인
-```sh
-git branch
-```
-
-#### 2. 변경 사항 확인
-```sh
-git status
-```
-
-#### 3. 변경된 파일 추가
-```sh
-git add .
-```
-
-#### 4. 커밋 메시지 작성
-```sh
-git commit -m "Commit Message"
-```
-
-#### 5. 원격 저장소에 본인 브랜치로 푸시
-```sh
-git push origin <브랜치명>
-```
-
-### Commit Convention
-
-커밋 메시지는 `타입: n주차 미션 설명`의 형식을 갖추어 작성합니다.
-
-| 타입 | 설명 |
-|-----------|--------------------------------|
-| feat | 새로운 기능 추가 |
-| fix | 버그 수정 |
-| refactor | 코드 리팩토링 |
-| docs | 문서 수정 (README 등) |
-| style | 코드 스타일 변경 (세미콜론 추가 등)|
-| chore | 빌드 및 패키지 설정 변경 |
-| test | 테스트 코드 추가 |
-
-#### Commit Example
-```sh
-git commit -m "feat: 1주차 미션 화면 전환 기능"
-git commit -m "fix: 5주차 미션 API 응답 오류 수정"
-```
-
-### PR Convention
-
-- Pull Request(PR)은 미션 별로 생성합니다.
-- PR 제목은 `n주차 미션` 형식으로 작성합니다.
-- 파트장이 승인한 후, main 브랜치로 Merge 합니다.
