+
+## 1. 환경설정
+
+### pyenv 설치
+>pyenv는 여러 python 버전을 한 컴퓨터에서 관리 및 사용할 수 있게 해준다.  
+설치에는 다음의 링크를 참고하자.  
+[GitHub-pyenv](https://github.com/pyenv/pyenv?tab=readme-ov-file#installation)  
+
+어차피 구체적인 환경은 venv를 사용할 예정이므로, pyenv를 통해 설치하는 python은 Global로 설정해도 된다.  
+```bash
+pyenv global 3.12 # [email protected]를 global하게 사용(설치)
+```  
+<br>
+
+### venv
+>venv는 가상환경을 제공해서 워킹디렉토리 별로 python 버전 관리 및 의존성을 따로 관리할 수 있도록 해준다.  
+
+<br>
+
+### jupyter lab, notebook 설치
+[Jupyter Install](https://jupyter.org/install)를 참고하여 주피터 랩과 노트북을 설치한다.  
+<br>
+
+### jupyter notebook, venv에서 실행하기
+주피터를 이대로 실행하게 되면 Global로 설정된 pyenv를 사용하고 후에 설치하게 될 모든 의존성도 그곳에 모이게된다.  
+이렇게 될 경우 venv의 이점을 다 누리지 못하므로 우리는 pyenv 대신 venv를 통해 주피터를 사용할 수 있게 설정한다.  
+<br>
+>pyenv(global)가 아닌 venv(local)에 패키지 설치하고 사용하기
+파이썬이 어디서 실행되는지 알려면 간단하게 which를 사용해볼 수 있다.  
+```
+which python
+```  
+![figure-1](assets/figure-1.png)  
+현재 global로 설정된 pyenv의 [email protected]를 찾아오고 있다.  
+우리는 이를 venv로 교체한다.  
+<br>
+W1 폴더에 venv를 만들어준다.  
+```bash
+python -m venv <working-directory>
+```
+![figure-2](assets/figure-2.png)  
+<br>
+가상환경을 활성화한다.  
+```bash
+source <working-directory>/bin/activate
+```
+![figure-3](assets/figure-3.png)  
+<br>
+이제 주피터 노트북과 venv를 연결해줘야 한다.  
+ipykernel을 설치하자.   
+- ipykernel도 가상환경 밑에 설치되도록, activate 이후 설치한다.  
+```bash
+pip install ipykernel
+```
+<br>
+
+커널을 하나 만들어준다. 추가할 가상환경과 주피터에서 display할 이름을 정의한다.  
+```bash
+python -m ipykernel install --user --name [가상환경폴더] --display-name [Jupyter에서 보여질 이름]
+# python -m ipykernel install --user --name W1 --display-name W1-venv
+```
+
+<br>
+
+주피터 실행 후 ipynb 파일을 생성하고 커널을 변경한다.  
+![figure-4](assets/figure-4.png)  
+
+<br>
+
+새로운 패키지를 설치해보고 올바른 위치(venv)에 깔리는지 확인하자.  
+![figure-5](assets/figure-5.png)    
+
+<br>
+
+#### 부록.
+현재 존재하는 커널 리스트를 확인하고 삭제하는 방법  
+```bash
+# List all kernels and grap the name of the kernel you want to remove
+jupyter kernelspec list
+# Remove it
+jupyter kernelspec remove <kernel_name>
+```  
+
+<br>
+
+##### 참고.
