+# 🚀미션 - 페어매칭관리 애플리케이션
+
+## 진행방식
+
+- 미션은 기능 요구 사항, 프로그래밍 요구 사항, 과제 요구 사항 세가지로 구성되어 있다.
+- 세 개의 요구 사항을 만족하기 위해 노력한다.
+
+---
+
+### 💙구현 목표
+
+- 위아래 둘 중 하나의 칸만 건널 수 있는 다리를 끝까지 건너가는 게임이다.
+
+### 📜구현 동작
+
+1. 보기 중에서 원하는 기능을 선택한다.(숫자로 입력)
+2. 과정, 레벨, 미션을 출력한다.
+3. 과정, 레벨, 미션을 입력한다.(ex. 백엔드, 레벨1, 자동차경주)
+4. 페어 매칭 결과를 출력한다.
+5. Q(종료)를 입력하면 미션이 종료된다.
+
+---
+
+## 🔍구현 로직
+
+- ### Main diagram
+
+
+
+- ### Util diagram
+
+
+
+- ### View diagram
+
+---
+
+## ✅기능 목록 checkList
+
+- [ ] 1.기능 선택
+  - [ ] 프로그램이 시작하면 기능의 종료를 출력한다.
+  - [ ] 기능의 종료를 출력하고, 그 중 하나를 입력 받는다.
+- [ ] 2.페어 매칭 기능 구현
+  - [ ] 과정과 미션에 대한 내용을 출력한다.
+  - [ ] 매칭하고자 하는 과정, 레벨, 미션을 입력 받는다.
+  - [ ] 매칭이 정상적으로 수행되면 결과가 출력된다.
+- [ ] 3.페어 조회 기능 구현
+  - [ ] 매칭 이력이 있으면 해당 미션의 페어 정보를 출력한다.
+  - [ ] 매칭 이력이 없으면 매칭 이력이 없다는 에러 메세지를 출력한다.
+- [ ] 4.페어 초기화 기능 구현
+  - [ ] 페어 초기화 숫자를 입력하면 페어 미션에 대한 정보가 초기화 된다.
+  - [ ] 초기화 되었다는 내용을 출력한다.
+- [ ] 종료(Q)를 입력하면 게임이 종료된다.
+
+## ✅추가할 객체
+
+1. 
+
+## ✅예외 처리
+
+- 사용자가 잘못된 값을 입력할 경우 IllegalArgumentException를 발생시키고,
+  - [ERROR]로 시작하는 에러 메시지를 출력 후 해당 부분부터 다시 입력을 받는다.
+- [ ] 1.기능을 선택하는 숫자를 입력할 때, 1~3 이외에 다른 숫자를 입력하는 경우
+  - [ ] Q 이외에 다른 문자를 입력하는 경우
+- [ ] 2.과정, 레벨, 미션에 있는 단어 이외에 다른 단어를 입력하는 경우
+- [ ] 3.페어 조회 기능에서 "네 | 아니오" 를 제외한 다른 단어를 입력하는 경우
