+### <간단한 로또 발매기 구현>
+
+- 로또 번호의 숫자 범위는 1~45
+- 로또 구입 금액 입력 시 구입 금액에 해당하는 만큼 로또 발행
+    - 로또 1장의 가격은 1,000원
+    - 1,000원으로 나누어 떨어지지 않는 경우 예외 처리
+    - 1장의 로또 발행 시 중복되지 않는 6개의 숫자 선정
+    - 로또 번호는 오름차순으로 정렬하여 출력
+- 당첨 번호 추첨
+    - 중복되지 않는 6개의 숫자와 보너스 번호 1개 선정
+- 당첨에는 1~5등 존재
+    - 당첨 기준과 금액
+        - 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
+- 당첨 번호와 보너스 번호를 입력받음
+- 사용자가 구매한 로또 번호와 당첨 번호 비교
+    - 당첨 내역 및 수익률을 출력한 뒤 로또 게임 종료
+    - 수익률은 소수점 둘째 자리에서 반올림
+- 사용자가 잘못된 값을 입력할 경우 `IllegalArgumentException` 발생
+    - `[ERROR]`로 시작하는 에러 메시지 출력
+    - 그 부분부터 입력을 다시 받음
+    - `Exception`이 아닌 `IllegalArgumentException`, `IllegalStateException` 등과 같은 명확한 처리
+- `camp.nextstep.edu.missionutils`에서 제공하는 `Randoms`, `Console API` 사용
+- Random 값 추출은 `camp.nextstep.edu.missionutils.Randoms`의 `pickUniqueNumbersInRange()` 활용
+- 사용자 입력 값은 `camp.nextstep.edu.missionutils.Console`의 `readLine()`을 활용
+
+## 📃 추가된 프로그래밍 요구 사항
+
+- - -
+
+- 메서드의 길이가 15라인을 넘어가지 않도록 구현
+- 메서드가 한 가지 일만 잘 하도록 구현
+- `else`, `switch`/`case` 금지
+    - `if` 조건절에서 값을 `return`하는 방식으로 구현하면 됨
+- Java Enum 적용
+- 구현한 기능에 대한 단위 테스트 작성
+    - 단, UI(`System.out`, `System.in`, `Scanner`) 로직 제외
+    - 단위 테스트 작성이 익숙하지 않다면 `LottoTest` 참고

+## 💡 구현할 기능 목록
+
+- - -
+
+### 1. 입력
+
+- [ ] 로또 구입 금액 입력 받기
+    - [ ] 1,000원 단위로 입력 받아야 함
+    - [ ] 1,000으로 나누어 떨어지지 않는 경우 예외 발생
+    - [ ] 양의 정수가 아닌 경우 예외 발생
+    - [ ] 1회 최대 구매 가능 금액을 초과할 시 예외 발생
+- [ ] 당첨 번호 입력
+    - [ ] 쉼표로 구분
+        - [ ] 올바르게 구분할 수 없을 시 예외 발생
+    - [ ] 6개 입력 받음
+        - [ ] 6개 초과 시 예외 발생
+    - [ ] 1~45 범위의 정수만 있는지 검증
+        - [ ] 범위 외의 수 입력 시 예외 발생
+    - [ ] 중복 없이 입력되었는지 검증
+        - [ ] 중복되었을 시 예외 발생
+- [ ] 보너스 번호 입력
+    - [ ] 1개 입력 받음
+    - [ ] 1~45 범위의 정수인지 검증
+    - [ ] 범위 외의 수 입력 시 예외 발생
+
+### 2. 로또 발행
+
+- [ ] 발행할 로또 수량 계산
+- [ ] 로또 번호 선정
+    - [ ] 1~45 범위의 정수 중 중복 없이 무작위 6개의 숫자
+    - [ ] 각 로또마다 오름차순으로 번호 정렬
+- [ ] 로또 리스트 생성
+    - [ ] 구입 금액에 따라 계산된 수만큼의 로또 생성
+        - [ ] 리스트에 저장
+    - [ ] 생성된 로또 리스트를 형식에 맞게 출력
+
+### 3. 당첨 결과 계산
+
+- [ ] 각 로또의 번호와 당첨 번호를 비교
+    - [ ] 일치하는 번호의 개수 계산
+- [ ] 당첨 등수 판단
+    - [ ] 일치하는 번호의 개수에 따라 등수 결정
+- [ ] 각 등수의 당첨 횟수 카운팅
+- [ ] 당첨 횟수 저장
+
+### 4. 수익률 계산
+
+- [ ] 총 당첨금 계산 (각 등수별 당첨 횟수 * 당첨금)
+- [ ] 수익률 계산 (총 당첨금 / 총 구입 금액) * 100
+    - [ ] 소수점 둘째 자리에서 반올림
+
+### 5. 결과 출력
+
+- [ ] 로또 구매 내역(생성된 로또 수와 각 로또의 번호를 오름차순 정렬) 출력
+- [ ] 당첨 통계(등수별 당첨 횟수와 당첨금) 출력
+- [ ] 계산된 수익률 출력
+
+### 6. 단위 테스트 작성
+
+- [ ] 구현한 기능에 대한 단위 테스트 작성
+
+### 7. 유틸리티
+
+- [ ] 숫자 검증 유틸리티
+- [ ] 숫자 랜덤 추출 유틸리티
+- [ ] 오름차순 정렬 유틸리티
+
+### 8. 구조 개선 및 리팩토링
+
+- [ ] 메서드 분리
+    - [ ] 메서드의 길이가 15라인을 넘어가지 않도록 구현
+    - [ ] 메서드가 한 가지 일만 잘 하도록 구현
+- [ ] 책임 분리: 각 클래스가 단일 책임 원칙을 따르도록 구조 개선
+- [ ] else, switch/case문 금지
+- [ ] Enum의 적용
+
+## 🤔 생각의 흔적
+
+- - -
+
+### 로또의 흐름
+
+1. 로또 구입 금액 입력 받음
+2. 당첨 번호 입력 받음
+3. 보너스 번호 입력 받음
+4. 발행한 로또의 수량 출력
+5. 발행한 로또의 번호를 오름차순으로 정렬하여 출력
+6. 당첨 내역 출력
+7. 수익률 출력
+
+- 예외 상황 시 에러 문구 출력 후 다시 입력 받음
+
+### 고민한 부분
+
+- 로또 구매 가능 금액을 int나 long으로 할 것인가, 현실처럼 10만 원까지 제한할 것인가
+- 선정된 로또 번호 출력 시 너무 길어지지 않도록 하되, 10만 원 보다는 넉넉하게 제한
