+
+Step1 : 연락처 추가
+
+[제시된 기능요구사항]
+
+[목표]
+: 간단한 연락처를 구현한다.
+* 연락처를 추가한다.
+* 이름과 전화번호는 필수 값이다.
+    * 입력하지 않으면 토스트 메시지를 보여준다.
+* 전화번호 입력은 숫자만 가능하다.
+* 더보기를 눌러 입력 폼을 확장할 수 있다.
+    * 생일, 성별, 메모 입력 폼이 등장한다.
+    * 성별을 둘 중 하나를 선택할 수 있다.
+* 저장 버튼을 누르면 '저장이 완료 되었습니다' 라는 토스트 메시지를 보여준다.
+* 취소 버튼을 누르면 '취소 되었습니다' 라는 토스트 메시지를 보여준다.
+
+[나누어진 커밋 단계]
+1. doc : ReadMe 파일 추가
+2. feat : 레이아웃 추가 (UI추가)
+3. feat : 이름과 전화번호를 입력하지 않을시 토스트 메시지 보내기 구현
+4. feat :더보기를 누를시, 입력폼 확장 구현
+5. feat : 이름과 전화번호를 누를시, ‘저장완료’ 토스트 메시지 보내기 구현
+6. feat : 취소 버튼을 누를시, ‘취소완료’ 토스트 메시지 보내기 구현
+
+
+Step2 : 연락처 목록
+
+[제시된 기능 요구 사항]
+목표 : 간단한 연락처를 구현한다.
+
+연락처 등록 화면을 구현한다.
+연락처를 저장하면 목록에 추가된다.
+저장된 연락처가 많을 경우 목록은 스크롤 되어야 한다.
+추가된 연락처를 선택하여 상세 화면을 볼 수 있다.
+연락처 작성 중 뒤로가기 버튼을 누르면 확인 팝업이 나타난다.
+추가된 연락처는 앱을 다시 실행하면 유지되지 않는다.
+
+1. 연락처 등록 화면 구현
+2. 연락처 저장시, 목록에 추가 기능 구현
+3. 목록 화면 구현
+4. 연락처 목록에서 상세페이지 화면 구현
+5. 상세페이지 보기 기능 구현
