# DNS Configuration

* Here are the steps to configure your DNS :
* Log in to your hosting provider and find the "DNS Zone" section.
* Add two entries with a "NS" (Name Server) pointing field.
* In the first entry, add your previously chosen subdomain from your GTM settings into the "Target" field: ns1.gtm-helper.com
* In the second entry, do the same for the subdomain, but add ns2.gtm-helper.com into the "Target" field.
