In this chapter, we learned about JupyterLab extensions and how to install them using the extension manager and the Terminal. We also explored the capabilities of the plugin, mime renderer, theme, and core extensions. We learned how to develop JupyterLab extensions by creating a development environment, repository, and extension project and checking our work within the developer console.

In the next chapter, we will learn how extensions can help with data exploration within JupyterLab.
