Netlify

Log in to your Netlify account and access the "Domain" section

Click on your domain to view DNS settings

In the DNS records section, you can add the two NS records below

Name: HOSTNAME - in your Sirdata console (adding the domain is optional)

Value: ns1.gtm-helper.com + ns2.gtm-helper.com

Once the DNS configuration is complete, wait for DNS propagation (can take up to 24 hours)
