Remove subdomain codes

README.md

 
 Both of the IP addresses are local IP addresses, typically of the form 192.168.x.x, with one being for the system and the other being for the internet router.
 
-If you are using FreeDNS as a dynamic DNS provider then you can add the following to your configuration file, setting the subdomain codes as appropriate. You can find the codes on the FreeDNS site under "Dynamic DNS" followed by "quick cron example" then look for the code on the last line between the ? and = characters.

 Save the configuration file and exit from your editor.
 
 Now you can begin the installation. If you are doing this on a Beaglebone Black:
 
     freedombone -d [default domain name] -u [username] --ddns [dynamic DNS provider domain] --ddnsuser [dynamic DNS username] --ddnspass [dynamic DNS password]
 
-The above command should be run in the same directory in which your configuration file exists. You can use any of your domains as the default one, but typically the default domain is the same as the one for your wiki. If you are using FreeDNS as the dynamic DNS provider then also add the -c option to specify the code corresponding to the subdomain.
+The above command should be run in the same directory in which your configuration file exists. You can use any of your domains as the default one, but typically the default domain is the same as the one for your wiki.
 
 Also see the manpage for additional options which can be used instead of a configuration file. If you don't specify a variant type with the final option then everything will be installed. If you have a *freedombone.cfg* file then it should be in the same directory from which the *freedombone* command is run.

-# Summary
-# =======
-#
-# This script is intended to be run on the target device, which
-# is typically a Beaglebone Black.
-#
-# To be able to run this script you need to get to a condition
-# where you have Debian Jessie installed, with at least one
-# unprivileged user account and at least one subdomain created on
-# https://freedns.afraid.org/. If you're not installing on a
-# Beaglebone Black then set the variable INSTALLING_ON_BBB to "no"
-#
-# Note on dynamic dns
-# ===================
-#
-# I'm not particularly trying to promote freedns.afraid.org
-# as a service, it just happens to be a dynamic DNS system which
-# provides free (as in beer) accounts, and I'm trying to make the
-# process of setting up a working server as trivial as possible.
-# Other dynamic DNS systems are available, and if you're using
-# something different then comment out the section within
-# argument_checks and the call to dynamic_dns_freedns.
-#
-# Prerequisites
-# =============
-#
-# You will need to initially prepare a microSD card with a Debian
-# image on it. This can be done using the initial_setup.sh script.
-#
-# If you are not using a Beaglebone Black then just prepare the
-# target system with a fresh installation of Debian Jessie.
-#
-# Configuration file
-# ==================
-# If you don't want to edit this script directly then you can
-# create a configuration file called freedombone.cfg, which should
-# be in the same directory as install-freedombone.sh.
-# Within the configuration file you can specify the main settings
-# such as:
-#
-# INSTALLING_ON_BBB=yes
-# SSH_PORT=2222
-# MICROBLOG_DOMAIN_NAME=mydomain
-# MICROBLOG_FREEDNS_SUBDOMAIN_CODE=[code]
-# ...
-#
-# Note that there are no spaces around the equals.
