Jupyter is included.

Once you have downloaded and extracted the binary bundle,
place an alias to the `sage`

executable somewhere in your path,
for instance by running this in the terminal (adapt `DIR`

as needed):

```
$ DIR=/home/you/SageMath
$ sudo ln -s $DIR/sage /usr/local/bin
```

This makes it easy to run Sage in the terminal by running `sage`

from anywhere.

To start Jupyter, use one of the following commands in the terminal:

```
$ sage -n jupyter
$ sage --jupyter notebook
```

Note: you can also install JupyterLab.

To install JupyterLab for Sage <= 9.2.beta10:

```
$ sage --pip install jupyterlab
```

To install JupyterLab for Sage >= 9.2.beta11:

```
$ sage -i jupyterlab_widgets
```

Then start it with one of the following commands in the terminal:

```
$ sage -n jupyterlab
$ sage --jupyter lab
```
