+#
+# kea-sdnc-notify-mod
+
+Kea module utilizing hooks api to notify SDNC of macaddr, yiaddr, dhcp-msg-name via HTTP POST request.
+
+# ONAP installation of vDHCP will intall and configure on the vDHCP VM
+#
+# for local development/testing follow these steps.
+#
+
+#
+# install kea on ubuntu
+apt-get install  kea-dhcp4-server
+
+
+#
+# Usage
+Install the compiled library from the ./build direction to  /usr/local/lib/kea-sdnc-notify.so
+
+Configure /etc/kea/kea-sdnc-notify.conf using the ./etc example
+
+Configure /etc/kea/kea-dhcp4.conf usign the ./etc example
+
+The hook will POST json from the the variables from the DHCP Acknowledgement message to the SDNC "url" in the form of "url+macaddr"
+"url": "http://localhost/sdnc.php?macaddr="
+
+Example: http://localhost/sdnc.php?macaddr=aa:bb:cc:dd:ee:ff
+
+In the ONAP installation instead of localhost it will be to either a DMaaP Topic or to SDNC directly.
+
+
+## START DHCP
+[as root]
+cd /etc/init.d 
+./kea-dhcp4-server start or
+./kea-dhcp4-server restart 
+
+./kea-dhcp4-server stop 
+
+## logs are in 
+/var/log/kea-dhcp4.log
+
+## Build requirements
+This software has been developed on Ubuntu 16.04.  
+
+apt-get install g++ libcurl4-gnutls-dev libboost-dev kea-dev
+
+./build.sh
+
+## Intallation in  ONAP
+The vdhcp install scripts for ONAP will do the build on the vDHCP VM from these source files and copy the resulting library into /usr/local/lib and the configuration files into /etc/kea
+
+## Testing locally
+
+#### USE THIS ON OPENSTACK UBUNTU 16.04 GUEST VM
+
+Create a veth pair:
+
+ip link add veth0 type veth peer name veth1
+
+ip link set veth0 up && ip link set veth1 up
+
+ip address add dev veth0 10.3.0.1/24
+
+dhclient -d -v veth1
+
+dhclient -d -v veth1 -r (to release)
