#
# First go to GoDaddy developer site to create a developer account and get your key and secret
#
# https://developer.godaddy.com/getstarted
# Be aware that there are 2 types of key and secret - one for the test server and one for the production server
# Get a key and secret for the production server
#
#
#Create a godaddy_keys file with the lines
#
# KEY <godaddy dev API KEY>
# SECRET <godaddy dev SECRET>

#
#Update the first 4 variables with your information
