+## 📑 간단한 로또 발매기 구현하기
+
+### 구현할 기능 목록
+
+- 로또 번호의 숫자 범위는 1~45까지이다.
+- 1개의 로또를 발행할 때 중복되지 않는 6개의 숫자를 뽑는다.
+- 당첨 번호 추첨 시 중복되지 않는 숫자 6개와 보너스 번호 1개를 뽑는다.
+- 당첨은 1등부터 5등까지 있다. 당첨 기준과 금액은 아래와 같다.
+  - 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
+- 로또 구입 금액을 입력하면 구입 금액에 해당하는 만큼 로또를 발행해야 한다.
+- 로또 1장의 가격은 1,000원이다.
+- 당첨 번호와 보너스 번호를 입력받는다.
+- 사용자가 구매한 로또 번호와 당첨 번호를 비교하여 당첨 내역 및 수익률을 출력하고 로또 게임을 종료한다.
+- 사용자가 잘못된 값을 입력할 경우 "[ERROR]"로 시작하는 메시지와 함께 Error를 발생시키고 해당 메시지를 출력한 다음 해당 지점부터 다시 입력을 받는다.
+
+## ✏️ 요구 사항
+
+### 1) 입력
+
+- 로또 구입 금액을 입력 받는다. 구입 금액은 1,000원 단위로 입력 받으며 1,000원으로 나누어 떨어지지 않는 경우 예외 처리한다.
+
+  ```
+  14000
+
+  ```
+
+- 보너스 번호를 입력 받는다.
+
+  ```
+  7
+
+  ```
+
+### 2) 출력
+
+- 발행한 로또 수량 및 번호를 출력한다. 로또 번호는 오름차순으로 정렬하여 보여준다.
+
+  ```
+    8개를 구매했습니다.
+    [8, 21, 23, 41, 42, 43]
+    [3, 5, 11, 16, 32, 38]
+    [7, 11, 16, 35, 36, 44]
+    [1, 8, 11, 31, 41, 42]
+    [13, 14, 16, 38, 42, 45]
+    [7, 11, 30, 40, 42, 43]
+    [2, 13, 22, 32, 38, 45]
+    [1, 3, 5, 14, 22, 45]
+
+  ```
+
+- 당첨 내역을 출력한다.
+
+  ```
+    3개 일치 (5,000원) - 1개
+    4개 일치 (50,000원) - 0개
+    5개 일치 (1,500,000원) - 0개
+    5개 일치, 보너스 볼 일치 (30,000,000원) - 0개
+    6개 일치 (2,000,000,000원) - 0개
+
+  ```
+
+- 수익률은 소수점 둘째 자리에서 반올림한다. (ex. 100.0%, 51.5%, 1,000,000.0%)
+
+  ```
+  총 수익률은 62.5%입니다.
+
+  ```
+
+### 3) 에러 처리
+
+- 사용자가 잘못된 값을 입력할 경우 "[ERROR]"로 시작하는 메시지 출력
+
+```
+[ERROR] 로또 번호는 1부터 45 사이의 숫자여야 합니다.
+
+```
+
+## ⭕실행 결과 예시

+- @woowacourse/mission-utils에서 제공하는 Random 및 Console API를 사용하여 구현해야 한다.
+  - Random 값 추출은 Random. pickUniqueNumbersInRange()를 활용한다.
+  - 사용자의 값을 입력 및 출력하려면 Console.readLineAsync()와 Console.print()를 활용한다.
