Instructions to use delv to test DNS configured domain before DS uploaded to parent

[Brett Delmage]

I previously used delv with a manually made trust/key file to test that a 
DNSSEC-enabled zone was generated correctly.

Despite sarching for all kinds of terms I cannot find those instructions 
(in readthedocs I believe).

Could someone please point me there?

bind9, bind9-dnsutils: 9.18.15

Thanks.
