+## 💌 [미션 - 자동차 경주 게임] 기능 목록
+
+### 도메인 구성 요소
+
+- 자동차
+  - 이름
+  - 위치
+- 모든 자동차 목록
+- 자동차가 이동하기 위한 값 생성기
+- 시도 횟수
+- 게임 결과
+  - 우승한 자동차 이름 모음 (중복 가능)
+
+### 도메인 로직을 위한 기능
+
+1. 경주할 모든 자동차의 이름을 저장하는 기능
+   - [ ] `예외발생` : 이름의 길이가 5자 초과
+2. 랜덤 숫자 생성 기능
+3. 자동차가 전달 받은 숫자에 따라 이동하는 기능
+   - [ ] `예외발생`: 전달 받은 숫자가 범위 밖
+4. 자동차 간 위치를 비교해 값이 가장 큰, 1~n 명의 우승자를 정하는 기능
+5. 전달 받은 횟수만큼 자동차를 이동하는 기능
+
+     
+### UI 로직을 위한 기능
+
+1. 경주할 모든 자동차 이름을 형식에 맞게 입력 받는 기능
+   - [ ] `예외발생` : 빈 문자열
+   - [ ] `예외발생` : 입력값 형식에 맞지 않음
+2. 시도할 횟수를 입력 받는 기능
+   - [ ] `예외발생` : 자연수가 아닌 값
+3. 차수별 실행 결과 출력
+4. 우승자 안내 문구 출력
+5. 이름 형식을 쉼표 구분 <-> 리스트로 파싱
+6. 에러 메시지 출력
+7. 잘못된 값 입력 시 그부분부터 재입력
