+## 프로그램 흐름
+
+- 사용자로부터 게임 시작 여부를 입력받는다.
+    - `start`를 입력받으면 게임을 생성하고 초기 체스판의 상태를 출력한다.
+    - `end`를 입력받으면 프로그램을 종료한다.
+- 기물 이동 여부를 입력받는다.
+    - `move b2 b4`와 같이 입력받으면 `b2`에 존재하는 기물을 `b4`로 이동시킨다.
+    - `end`를 입력받으면 프로그램을 종료한다.
+
+## 도메인별 기능
+
+### Piece
+
+- [x] 출발지 & 목적지 정보를 토대로 기물이 이동할 수 있는지 검사한다.
+- [x] 입력받은 색상을 토대로 자신의 적 여부를 반환한다.
+
+#### Rook
+
+- 상/하/좌/우 거리 제한 없이 이동 가능
+- 비었거나 적 기물이 존재하는 칸으로만 이동 가능
+- 이동 경로에 기물이 존재하면 이동 불가
+
+#### Bishop
+
+- 대각선 방향 거리 제한 없이 이동 가능
+- 비었거나 적 기물이 존재하는 칸으로만 이동 가능
+- 이동 경로에 기물이 존재하면 이동 불가
+
+#### Queen
+
+- 상/하/좌/우, 대각선 방향 거리 제한 없이 이동 가능
+- 비었거나 적 기물이 존재하는 칸으로만 이동 가능
+- 이동 경로에 기물이 존재하면 이동 불가
+
+#### King
+
+- 상/하/좌/우, 대각선 방향 중 한 칸만 이동 가능
+- 비었거나 적 기물이 존재하는 칸으로만 이동 가능
+
+#### Knight
+
+- 상/하/좌/우 중 한 칸 이동 후 전진 방향의 대각석으로 한 칸 이동 가능
+- 비었거나 적 기물이 존재하는 칸으로만 이동 가능
+- 이동 경로에 기물이 존재해도 이동 가능
+
+#### Pawn
+
+- 특정 조건에 따라 이동 선택
+    - 기본적으로 한 칸 전진 가능
+    - 출발지가 초기 위치일 경우 두 칸 전진 가능
+    - 전진 경로 혹은 목적지에 기물이 존재하면 이동 불가
+    - 전진 방향 대각선 한 칸에 적 기물이 존재시 이동 가능
+
+## Board
+
+- [x] 특정 색상의 기물 이동
+    - `출발지` == `도착지`인 경우 예외 처리
+    - 출발지에 기물이 존재하지 않으면 예외 처리
+    - 상대 색상의 기물을 이동시키려 할 시 예외 처리
+
+## ChessGame
+
+- [x] `흰색` 플레이어와 `검은색` 플레이어의 게임 순서 관리 및 `Board`에 기물 이동 요청 전달
