-# Ansible role for NSD
+# This is a modified version of "Ansible role for NSD"
+
+Original source: https://github.com/zorun/ansible-role-nsd/
+
+I have made several changes to fit my usecase (essentially remote control and dnssec specificities, as well as some cosmetic changes).
+
+Changes: added two new dictionaries:
+
+* **nsd_remote_control** for remote controllong options in the config file
+* **nsd_zone_subdirs** to transfer whole subdirectories (I expect each one to contain a source.sh script which signs dnssec, installed as a cron)
+
+----
 
 This Ansible role installs and configure NSD, an authoritative DNS server.
 It also allows to publish DNS zones into NSD.
