Copy this entire gist to your raspberry pi
Do chmod +x step1.sh step2.sh iptables.sh in the gist folder (so that
Run step1.sh a) This script does a few things - it first updates your raspberry pi, then it installs a few needed utilities, then it upgrades the firmware on your raspberry pi

	# THE SETUP

	# Mail will be stored in non-retarded Maildirs because it's $currentyear. This
	# makes it easier for use with isync, which is what I care about so I can have

	# The mailbox names are: Inbox, Sent, Drafts, Archive, Junk, Trash

	# In prior to edit this file manually by your text editor,
	# shutdown the VPN Server / Client / Bridge background service.
	# Otherwise, all changes will be lost.
