+- 개요: 간단한 로또 발매기 프로그램
+- 프로그램 흐름 (사용자 입장)
+  - 구입 금액 입력
+  - 구입 금액에 따라 발행된 로또 개수 및 로또별 번호 확인
+  - 당첨 번호 입력
+  - 보너스 번호 입력
+  - 당첨 통계(당첨 내역 및 수익률) 확인
+- 당첨 정책
+  - 1등: 6개 번호 일치 / 2,000,000,000원
+  - 2등: 5개 번호 + 보너스 번호 일치 / 30,000,000원
+  - 3등: 5개 번호 일치 / 1,500,000원
+  - 4등: 4개 번호 일치 / 50,000원
+  - 5등: 3개 번호 일치 / 5,000원 
+  
+## 실행 결과 예시

+
+## 기능 목록
+- [X] 로또 구입 금액 입력값 검증
+  - 입력 형식이 숫자여야 함
+  - 로또 1장의 가격(1000원)으로 나누어 떨어져야 함 
+- [x] 구입 금액에 해당하는 로또 수 계산
+- [x] 중복되지 않는 무작위 번호 6개로 구성된 단일 로또 발행
+  - 단, 로또 번호 정렬
+- [x] 로또 수 만큼 로또 발행
+- [x] 문자열 입력값에서 당첨 번호 추출
+  - 쉼표 기준으로 구분
+- [x] 입력 받은 보너스 번호 검증 
+  - 당첨 번호 입력값들과 중복되면 안 됨 
+- [x] 로또 번호의 숫자 범위 검증 (1~45)
+- [x] 로또 번호 개수 검증
+- [x] 당첨 번호 추첨 (중복되지 않는 숫자 6개와 보너스 번호 1개)
+- [x] 발행된 로또 수량 및 번호 출력
+- [x] 사용자가 구매한 로또 번호와 당첨 번호를 비교
+- [x] 당첨 내역 계산
+- [x] 당첨 내역 출력
+- [x] 총 상금 계산
+- [x] 수익률 계산
+- [x] 수익률 출력
+  - 소수점 둘째 자리에서 반올림 (ex. 100.0%, 51.5%, 1,000,000.0%)
+
+- [ ] 사용자가 잘못된 값을 입력할 경우 `IllegalArgumentException` 발생, 에러 메시지 출력 후 그 부분부터 입력을 다시 받기
+  - 단, 출력 메세지는 "[ERROR]"로 시작
