> Jupyter, JupyterLab, and IPython are already included in the project requirements by default, so once you have run `pip install -r requirements.txt` you will not need to take any extra steps before you use them.
### Jupyter
To use Jupyter notebooks in your Kedro project, you need to install Jupyter:

```
pip install jupyter
```

After installing Jupyter, you can start a local notebook server:

```
kedro jupyter notebook
```

### JupyterLab
To use JupyterLab, you need to install it:

```
pip install jupyterlab
