 # deeply-copy
-custom deep copy function to make a brand new immutable object
+
+A custom deep copy function to make a brand new immutable object. It handles copying self reference object or array. It supports dual packages (CJS/ESM)
+
+깊은 복사를 해 불변 객체로 반환한다. 모든 데이터 타입 복사가 가능하고, 객체나 배열의 순환 참조도 핸들링한다. 듀얼 패키지를 지원한다.
+
+# 프로젝트 인스톨 방법
+
+[pnpm 설치](https://pnpm.io/installation) 후 `pnpm install` 실행
+
+# Dual Package (CJS/ESM) 지원
+
+듀얼 패키지 지원을 위한 라이브러리나 모듈러를 별도로 사용하지 않고, TSC와 pacakge.json만을 사용하여 CJS, ESM을 모두 지원하고 있음.
