 The Docker container executes a [`start-notebook.sh` script](./start-notebook.sh) script by default. The `start-notebook.sh` script handles the `NB_UID`, `NB_GID` and `GRANT_SUDO` features documented in the next section, and then executes the `jupyter notebook`.
 
+You can launch [JupyterLab](https://github.com/jupyterlab/jupyterlab) by setting `JUPYTER_ENABLE_LAB`:

+```
