 ====== Headless setup ======
-===== Prerequisites =====
+This is a step-by-step guide of how to test ODROID boards. It assumes that you want to run "headless", that is, access it via network connections without a keyboard or display. This guide is based on Hardkernel's Ubuntu environment.
+===== Assumetions =====
+You **HAVE**:
+  * ODROID-XU4
+  * SD card //or// eMMC (installed Ubuntu)
+  * Ethernet cable
+  * Linux PC
+  * A switching hub
+  * DHCP network
+You do **NOT** have:
+  * USB keyboard
+  * USB-UART Module Kit
+  * HDMI cable/monitor
 ===== Boot the ODROID and find IP address =====
+Connect the ODROID to a spare Ethernet port on your switching hub using an Ethernet cable.
+Insert the SD card(or eMMC) into the ODROID-XU4.
+Turn on the ODROID-XU4. Wait about 30 seconds.
+Ping scan to update ARP table:
+<code>
+brian@brian-desktop:~$ nmap -sn 192.168.100.0/24
+Starting Nmap 7.01 ( https://nmap.org ) at 2016-05-17 15:09 KST
+Nmap scan report for 192.168.100.1
+Host is up (0.00066s latency).
+Nmap scan report for 192.168.100.2
+Host is up (0.000084s latency).
+Nmap scan report for 192.168.100.3

+Host is up (0.00066s latency).
+Nmap scan report for 192.168.100.68
+Host is up (0.095s latency).
+Nmap done: 256 IP addresses (5 hosts up) scanned in 2.43 seconds
+brian@brian-desktop:~$
+</code>
+Check the ODROID-XU4 IP address: (NOTE: "00:1e:06" is start MAC address for ODROID boards.)
+<code>
+brian@brian-desktop:~$ arp -a | grep 00:1e:06
+? (192.168.100.53) at 00:1e:06:33:0d:45 [ether] on enp0s25
+brian@brian-desktop:~$
+</code>
 ===== Login using ssh =====
+In a terminal in your Linux PC, type "ssh odroid@xxx.xxx.xxx.xxx", where "xxx.xxx.xxx.xxx" is the IP address you discovered in the previous step.
+It will then prompt for your password. Type in the default password **odroid**:
+<code>
+brian@brian-desktop:~$ ssh odroid@192.168.100.8
+The authenticity of host '192.168.100.8 (192.168.100.8)' can't be established.
+ECDSA key fingerprint is SHA256:BCqiwzdtSViFOSAbgNHw35avUvOTHikW+fx7N4v+Lv0.
+Are you sure you want to continue connecting (yes/no)? yes
+Warning: Permanently added '192.168.100.8' (ECDSA) to the list of known hosts.
+odroid@192.168.100.8's password:

+===== VNC Remote Desktop =====
+Connect to the ODROID-XU4 using ssh:
+<code>
+brian@brian-desktop:~$ ssh odroid@192.168.100.8
+The authenticity of host '192.168.100.8 (192.168.100.8)' can't be established.

+Edit /etc/lightdm/lightdm.conf file to enable auto-login: (password: **odroid**)
+<code>
+odroid@odroid:~$ sudo vi /etc/lightdm/lightdm.conf
+[sudo] password for odroid:
+odroid@odroid:~$ cat /etc/lightdm/lightdm.conf
+[SeatDefaults]
+autologin-user=odroid
+autologin-user-timeout=0
+odroid@odroid:~$
+</code>
+Reboot ODROID-XU4(type 'sudo reboot'):
+<code>
+odroid@odroid:~$ sudo reboot
+PolicyKit daemon disconnected from the bus.
+We are no longer a registered authentication agent.
+Connection to 192.168.100.8 closed by remote host.
+Connection to 192.168.100.8 closed.
+</code>
+Connect to the ODROID-XU4 using ssh.
+Install vnc server using apt-get package management:
+<code>
+odroid@odroid:~$ sudo apt-get update
+odroid@odroid:~$ sudo apt-get install x11vnc
+</code>
+Run vnc server(type 'x11vnc'):
+<code>
+odroid@odroid:~$ x11vnc
+</code>
+Connect to the ODROID-XU4 VNC server from your Linux PC(type '//vncviewer <ODROID-XU4 IP address>:5900//'):
+<code>
+brian@brian-desktop:~$ vncviewer 192.168.100.8:5900
+</code>
