Custom domains, DNS, branded subdomains, and what happens when a business is renamed.

## Get started

- [Get started with domains](https://www.willo.ai/docs/domains/get-started): Every Willo site has a free bywillo.ai address from day one. Here is how that address works and when to connect a domain you own.

## Concept

- [DNS records for your domain](https://www.willo.ai/docs/domains/dns-records): Which DNS records point a domain at your Willo site, root domain versus subdomain, and how to leave your email records untouched.
- [Your site's official address](https://www.willo.ai/docs/domains/your-sites-address): How your site tells search engines, link previews and AI search which address is its real one, and what changes when a custom domain goes live.

## Guide

- [Connect a custom domain](https://www.willo.ai/docs/domains/connect-a-custom-domain): Point a domain you own at your Willo site, from entering it in Settings to HTTPS going live, without breaking the email on that domain.
- [Change or replace your domain](https://www.willo.ai/docs/domains/change-your-domain): Fix a mistyped domain, move to a new one after a rebrand, or remove a custom domain, and what visitors see while the change goes through.
