+# 구현 기능 목록
+
+- 몇 번 이동할 것인지 횟수 입력 기능
+- 자동차의 이름 입력 기능
+    - 쉼표(`,`) 기준으로 한 번에 n 대의 이름 입력 받기
+      - 해당 기능에서 자동차 갯수 확인
+    - 각각의 이름은 5자 이하
+- 자동차의 전진 기능
+  - 전진 조건은 0~9 사이 무작위 값이 4 이상일 경우
+- 각 실행 결과 출력 기능
+- 우승자 출력 기능 
+  - 우승자는 한 명 이상일 수 있음
+  - 쉼표(`,`)로 우승자 여러 명 출력
+- 잘못된 입력값에 대해 IllegalArgumentException 발생 기능
+
+# 프로그래밍 요구사항
+
+- 외부 라이브러리 사용 불가
+- `Kotlin Style Guide` 원칙
+- `indent depth` 2 이하로 구현할 것
+- 함수는 한 가지 일만 담당하게끔 구현
+- 위의 기능 목록에 대해 각각을 테스트할 것
