Customize CMS domain
To help your editors find the CMS URL, or to provide a more white-labeled solution, you can customize the URL of your project's CMS. Instead of the default yourproject.admin.datocms.com, you can use your own domain, like cms.mycompany.com.
To do so, first make sure the CNAME record of your domain's DNS points to admin.datocms.com, then go to your dashboard and follow along:
Please note that this domain only affects your CMS admin area, the place you normally go to edit your project and its models and records.
It does NOT affect the domain name for:
Your frontend (see How your website and DatoCMS work together )
Your DatoCMS account dashboard (dashboard.datocms.com)
