# Guides (https://dodomain.io/docs/guides)

Guides for adding custom domains to a multi-tenant app, for adding DNS records at each provider, and for how one-click setup works.

The guides go deeper than the reference pages. Some are for the developer wiring DoDomain into a product; some are for the person adding DNS records at a registrar. This page links every one of them, so it is the place to start whether you are reading or an agent is crawling.

How to pick one:

- **You build a multi-tenant product** and customers want `app.theirdomain.com`: read the framework guide for your stack.
- **Someone has to add DNS records** at a specific provider: open that provider's guide, or send it to them.
- **You want to know why one-click setup works at some providers and not others**: read the Domain Connect field notes.
- **You have not integrated yet**: start with [Getting started](https://dodomain.io/docs/getting-started).

## Framework guides [#framework-guides]

Each one covers the same four problems in the idioms of the framework: resolve the tenant from the request host, mint and verify the DNS records, receive the signed webhook, and place TLS.

## DNS provider guides [#dns-provider-guides]

One page per provider, with the vocabulary of that provider's own DNS panel: where the records live, what goes in the host field, and how to check the record is live. The [DNS provider setup guides](https://dodomain.io/docs/guides/dns-providers) hub has the same list with the root-domain entry and the date each guide was checked.

## Domain Connect [#domain-connect]

[Domain Connect field notes: every bug we hit](https://dodomain.io/docs/guides/domain-connect-field-notes) is the engineering write-up of shipping signed, one-click DNS applies over the open protocol: the template registry, the gaps in the spec, the provider bugs, and why a probe that answers 200 proves nothing.
