If you search the web for [nsupdate howto] or [nsupdate tutorial] you
should find some useful resources.
If you are running BIND 9.7 or newer then it has a built-in setup for
simple DNS UPDATE uses. Try adding the following line to your zone's
configuration:
update-policy local;
Then on your master server you can run
$ nsupdate -l
The nsupdate man page explains the input format. For most purposes you
only need to use "update add", "update delete", and "send", e.g. on my
server I can type
$ nsupdate -l

And my log says:
