-# springboot-jpa
-스프링부트 JPA 위클리미션을 코드리뷰하는 Repository입니다.
+# [Project] Springboot JPA Weekly Mission
+## 프로젝트 소개 😎
+스프링부트 JPA 위클리미션을 코드 리뷰하는 저장소 입니다.
+
+## 개발 환경
+- Language : Java 17
+- Framework : Springboot 3.1.2
+- ORM : JPA
+- Build Tool : Gradle
+- Dev Tool : IntelliJ, Docker
+- Test : JUnit 5
+- DB : MySQL, H2
 
 ### 이번 코드리뷰가 이루어지는 과정
 1. 백둥이끼리 코드리뷰를 진행합니다.
-2. 백둥이끼리의 코드리뷰가 마치면, 멘토님에게 2차 리뷰를 요청합니다.

+2. 백둥이끼리의 코드리뷰가 마치면, 멘토님에게 2차 리뷰를 요청합니다.
 
 ### 과제 번호
 - 미션1 : **2. JPA 소개(단일 엔티티를 이용한 CRUD를 구현)** 
 - 미션2 : **3. 영속성컨텍스트(customer 엔티티를 이용하여 생명주기 실습)**
 - 미션3 : **4-2. 연관관계매핑(order, order_item, item의 연관관계 매핑 실습)**    
-<br/>
 
 ### 코드리뷰 할 과제
 - 미션 1과 3은 코드리뷰를 진행해봅시다!
 - 미션 2의 코드리뷰 진행해도 스킵해도 됩니다. 스킵할 경우 실습해본 코드만 올려보세요 😀
 - 미션 2는 생명주기를 한 번 직접 코딩해보는 정도여서 리뷰는 필요없어도 될 것 같습니다.
-<br/>
 
 ### 코드리뷰가 마쳤다면! 만족할 코드가 완성되었다면! Merge!
 - merge하면서 conflict가 날 수 있겠죠? Git/Github 특강을 다시보며 해결해봅시다.
