+
+DnsProvider indicates that the specified provider should be used to manage
+records for this domain. The name must match the name used with [NewDnsProvider](../global/NewDnsProvider.md).
+
+The nsCount parameter determines how the nameservers will be managed from this provider.
+
+Leaving the parameter out means "fetch and use all nameservers from this provider as authoritative". ie: `DnsProvider("name")`
+
+Using `0` for nsCount means "do not fetch nameservers from this domain, or give them to the registrar".
+
+Using a different number, ie: `DnsProvider("name",2)`, means "fetch all nameservers from this provider,
+but limit it to this many.
+
+See [this page](../../nameservers.md) for a detailed explanation of how DNSControl handles nameservers and NS records.
+
+If a domain (`D()`) does not include any `DnsProvider()` functions,
+the DNS records will not be modified. In fact, if you want to control
+the Registrar for a domain but not the DNS records themselves, simply
+do not include a `DnsProvider()` function for that `D()`.
