-- [프로젝트 설명서](https://echoiing-fastcampus.notion.site/Smart-Store-47ea8a0b4b084301bd1eefbabe3426af)를 풀어서 제출하시오. 💻
-
-- 파일 이름 작성법 📂
-  - ````me.smartstore```` 패키지 생성
-- 제출방법 
-  - 본인의 이름으로 ````branch````를 생성하여 ````push````후 ````pull request```` 작성
-    - 예시 
-      - branch 이름 - ````FirstNameLastName````
-      - commit 메시지 (멘토 리뷰 이전) - [1차 VER1.0...] Java ToyProject upload by FirstNameLastName (labeling도 가능: ````first````)
-      - commit 메시지 (멘토 리뷰 이전) - [1차 VER2.0...] Java ToyProject upload by FirstNameLastName (labeling도 가능: ````second````)
-      - commit 메시지 (멘토 리뷰 이후) - [2차] Java ToyProject upload by FirstNameLastName (labeling도 가능: ````resubmit````)
-  - PR 메시지는 본인이 하고 싶은 말이나 질문을 적어주세요.
-    - ````코드리뷰 빡세게 부탁드립니다.```` ````클린한 코드인지 봐주세요.```` ````이 코드의 조금 더 나은 방법이 있을까요.````
-    - ````~~번 문제 풀지 못했습니다.```` ````~~번 문제 풀이 방법을 알려주시면 감사하겠습니다.````
-    - ````결과는 나왔는데 맞는지 모르겠습니다.```` 
-- 리뷰관련 [프로세스 🔖](https://quickest-asterisk-75d.notion.site/a8d233d87f0945cbaa8f71300515587d?p=b658d277f52843dd9e1e8322233c9006&pm=s)
-  - ```PEER REVIEW``` - 과제 기간동안 본인 과제 완료 후, 다른 수강생들의 PR을 보며 피어리뷰 가능 (댓글 이용) 
-  - ```MENTOR REVIEW``` - 과제 기간 이후에 멘토진 코드 리뷰 (댓글 이용)
-    - 멘토님이 작성한 댓글 이후에는 수강생이 댓글 자제 (혼선 막기 위함)
-- 주의사항 🔥
-  - 본인 ```branch``` -> ```main branch``` PR 상태로 제출부탁드립니다.
-  - ```main branch```에 본인 ```branch```의 ```commit```을 ```merge``` 하지 마시기 바랍니다.
-  - ```git ignore``` 활용 적극 권장 ‼ 
-    - 문제풀이 코드가 아닌 .idea, out과 같은 파일은 제출 하지 마세요 🥲
