## Domains

Domains allow you to use your own web addresses instead of the default system subdomain.

## Adding a Domain

To connect your own domain, add it in the account settings and configure DNS records:

- **A Record** — points the domain to the application server. Required to make the account accessible at your own URL
- **MX Record** — points mail to the mail server. Required to receive emails on your own domain

## Validation

After adding a domain, the system checks the DNS configuration:
- **A Validation** — confirms that the domain points to the correct server
- **MX Validation** — confirms that mail is correctly routed

The domain becomes active only after successful validation. System domains (e.g., `intum.pl`) are protected and cannot be validated.

## Primary Domain

One of the domains can be set as **primary** — used for building account URLs (e.g., links in emails, redirects).

## Assigning to Resources

A domain can be associated with:
- **CMS Website** — the domain leads to a specific website
- **Knowledge Base** — the domain displays a knowledge base

A single account can have multiple domains, and each domain can serve a different resource.
