-ExternalDNS's sources of DNS records live in package [source](../../source). They implement the `Source` interface that has a single method `Endpoints` which returns the represented source's objects converted to `Endpoints`. Endpoints are just a tuple of DNS name and target where target can be an IP or another hostname.
+ExternalDNS's sources of DNS records live in package [source](https://github.com/kubernetes-sigs/external-dns/tree/master/source). They implement the `Source` interface that has a single method `Endpoints` which returns the represented source's objects converted to `Endpoints`. Endpoints are just a tuple of DNS name and target where target can be an IP or another hostname.
 
 For example, the `ServiceSource` returns all Services converted to `Endpoints` where the hostname is the value of the `external-dns.alpha.kubernetes.io/hostname` annotation and the target is the IP of the load balancer or where the hostname is the value of the `external-dns.alpha.kubernetes.io/internal-hostname` annotation and the target is the IP of the service ClusterIP.

The registry is a wrapper and access point to DNS provider.
