```
forge install OpenZeppelin/openzeppelin-contracts
```

* foundry로 표준 구현체를 이용하기 위해서 라이브러리 설치를 진행해준다.

```
forge remappings > remapping.txt
```

* &#x20;설치한 contract를 import하고 사용자에 따라 추가적인 코드를 작성할 수 있다.
* remapping 설정을 해주었기에 @openzeppelin가 lib 폴더에 있는 openzeppelin-contracts 경로와 연결되어 @openzeppelin으로 간단하게 불러올 수 있다.
