Jupyter Notebook extensions are add-ons that can increase the functionality of your notebooks. Extensions include themes, editors, git support, renderers and much more. The most user-friendly way of managing extensions is via the Extension Manager available in the Jupyter lab interface. You can access it by clicking the puzzle piece icon in the left sidebar.

Warning!
Note that the extension manager contains a disclaimer warning you that these third-party extensions are not reviewed for vulnerabilities which means that you should be careful about what extensions you install.

You can use the search field to perform a free text search for available extensions, then click ‘Install’ to install an extension. Not that in some cases you will be prompted to install additional packages.

While an in-depth listing of available extensions is well beyond the scope of this tutorial we offer this list of a few extensions that are of particular relevance to this course:

Jupyterlab/GitHub - view and open files from GitHub
Jupyterlab/Git - version controlling with git
mamba-org/gator-lab - manage Conda environments
voila-dashboards/Jupyterlab-preview - preview a rendered version of your notebook
