To set up your domain, you’ll need to use an A Record for the root domain because GoDaddy doesn’t allow CNAMEs for the root (@). In your GoDaddy DNS settings, add an A Record with the name @ and point it to Railway's IP address, which you can find in their settings or documentation. This connects your root domain (myapp.com) directly to Railway.

For www.myapp.com, you’ll use a CNAME since subdomains can have CNAMEs. Add a CNAME record with www as the name and myapp.com as the value. This makes www.myapp.com point to the same place as the root domain.
