WPA/WPA2 configuration in Arch Linux on Raspberry Pi

With current Arch Linux on Raspberry Pi 1/2/3, configuring WiFi for WPA/WPA2 is as quick as:

1. Issue "wifi-menu" as root(a few seconds of scanning will take place)
2. A menu of broadcasted SSIDs will be displayed where you select your wireless network(See below for non-broadcasted SSIDs)
3. Enter the credentials which will create a profile in "/etc/netctl"(0600 mode owned by root)
4.  With 'netctl' now in-use on Arch Linux, you can say "netctl enable <SSID>" as superuser to start WiFi on boot.(adds a link to 'systemd' profiles that multi-user wants)

This will use 'dhcpd' to obtain an address. If you have a hidden/non-broadcast SSID, you'll need to create an entry in "wpa_supplicant.conf" with "scan_ssid" set to 1 among setting other options.(plenty of examples and option details exist in that file) For more info on dynamic or static config, visit Arch Linux's wireless network config page.
