Custom Domain

To use a custom domain with your documentation (docs.yoursite.com) instead of our hosted subdomain (yourdocs.hosted.docshub.io), you'll need to set up DNS records as follows:

For docs that DON'T require a login

If your documentation is public (you don't need a username/password or SSO to access the site), create a CNAME record pointing to cname.docshub.io, and then set up your custom domain through the DocsHub portal.

For docs that DO require a login

If your documentation is private (you need a username/password or SSO to access the site), create a CNAME record pointing to authcname.docshub.io, and then set up your custom domain through the DocsHub portal.
