# Overview

Instructors may use Amazon Web Services, a university domain, or any other domain service to add a custom domain.

{% hint style="info" %}
Adding your JupyterHub to a registered domain is necessary for running it in HTTPS.
{% endhint %}

This demonstration uses [Google Domains](https://domains.google/). If you have an existing custom domain, you may add the lab as a sub-domain as done here. This tutorial assumes an existing domain has been registered with Google Domains. Visit the [Google Domains Learning Center](https://domains.google/learning-center/) for more information on this.
