 Features

 **dehydrated-nsupdate** has the following features:
 
-| **automatic nameserver detection**
-| **dehydrated-nsupdate** automatically finds and updates all authoritative
-| nameservers for a given record by looking up the records in the DNS by itself,
-| supporting IPv6-only, IPv4-only, and dual-stacked environments.
+Automatic nameserver detection (IPv4 and IPv6)
+----------------------------------------------
+
+dehydrated-nsupdate automatically finds and updates all authoritative nameservers for a given record by looking up the records in the DNS by itself, supporting IPv6-only, IPv4-only, and dual-stacked environments.
+
+Proper CNAME support
+--------------------
+
+dehydrated-nsupdate follows CNAMEs delegating the TXT record update to another zone.
+
+Handling nameserver subzone shortcuts
+-------------------------------------
+
+dehydrated-nsupdate correctly handles authoritative nameserver answers that (wrongly) give shortcut answers for their own zones when using multiple authoritative subzones on the same nameservers.
+
+TSIG support
+------------
 
-| **proper CNAME support**
-| **dehydrated-nsupdate** follows CNAMEs delegating the TXT record creation to
-| another zone.
+dehydrated-nsupdate uses TSIG, if provided, to authenticate itself to the nameserver. Additionally to a global TSIG to be used for all record updates, separate TSIGs can individually be specified per record, per zone, and per nameserver.

+Proper removal of TXT records
+-----------------------------
 
-| **TSIG support**
-| **dehydrated-nsupdate** uses TSIG, if provided, to authenticate
-| itself to the nameserver.
+dehydrated-nsupdate removes records after succesfull verification.
+
+bind9-dnsutils and knot-dnsutils support
+----------------------------------------
+
+dehydrated-nsupdate works with both nsupdate (bind9) and knsupdate (knot).
+
+IDN handling
+------------
+
+dehydrated-nsupdate works with IDN domains by not expanding the punycode to update the correct records.
+
+Usage
+=====
 
-| **proper removal of TXT records**
-| **dehydrated-nsupdate** removes records after succesfull verification.
+dehydrated-hook(1) is a prerequisite for dehydrated-nsupdate.
 
-| **bind9-dnsutils and knot-dnsutils support*
-| **dehydrated-nsupdate** works with both nsupdate (bind9) and knsupdate (knot).
+Installation
+------------
 
-| **IDN handling**
-| **dehydrated-nsupdate** works with IDN domains by not expanding the punycode.
+| sudo echo CHALLENGETYPE="dns-01" > /etc/dehydrated/conf.d/zz-challengetype.sh
+| sudo ln -s /usr/bin/dehydrated-nsupdate /etc/dehydrated/hook.d/deploy_challenge.nsupdate
+| sudo ln -s /usr/bin/dehydrated-nsupdate /etc/dehydrated/hook.d/clean_challenge.nsupdate
+
+Removal
+-------
+
+| sudo rm -f /etc/dehydrated/conf.d/zz-challengetype.sh

+| sudo rm -f /etc/dehydrated/hook.d/clean_challenge.nsupdate
+
+Configuration
+=============
+
+Depending on the nameserver requirements, dehydrated-nsupdate can send record updates either unauthenticated or using a TSIG (recommended).
+
+A TSIG file consists of one single line containing the key (nsupdate/knsupdate do not allow comments), e.g.:
+
+|
+| hmac-sha512:example:/LXPy6U8HAWA+QmvulZWm0owsQgNf8qJ5MNLTvirzvVtDb+PzLKoBmVHjnL6TUffkvRYa7Do448dSIrAuJ1G/A==
+
+Instead of using a global TSIG for all record update, specific TSIGs can be used individually per record, zone, and nameserver.
+
+The lookup hierarchy is the following (earliest match wins):
+
+|
+| /etc/dehydrated/tsig/${record}.key
+| /etc/dehydrated/tsig/${zone}.key
+| /etc/dehydrated/tsig/${nameserver}.key
+| /etc/dehydrated/tsig.key
+|
+| TSIG_KEYFILE variable in /etc/default/dehydrated-nsupdate/*
+| TSIG_KEYFILE variable in /etc/default/dehydrated-nsupdate
+
+In order to explicitly not use a TSIG for a specific record, zone, or nameserver, an empty keyfile or a keyfile with only comments can be used, e.g.:
+
+|
+| echo "# disabled" > /etc/dehydrated/tsig/ns1.example.org.key
