A zone can be changed from insecure to secure in three ways: using a
-dynamic DNS update, or via the ``auto-dnssec`` zone option, or set a

DNSSEC policy for the zone with ``dnssec-policy``.
-For either method, ``named`` must be configured so that it can see
+For any method, ``named`` must be configured so that it can see
the ``K*`` files which contain the public and private parts of the keys
that are used to sign the zone. These files are generated

chain is generated as part of the initial signing process.
-With ``dnssec-policy you specify what keys should be KSK and/or ZSK.

If ``full``, the server collects statistical data on all zones,

default is ``terse``, providing minimal statistics on zones
(including name and current serial number, but not query type
counters).
