This tutorial assists users of the CuBox i4-Pro (using Freescale's iMX6 SoC) stand up a stable, serial-only version (no desktop/GUI) of Debian Wheezy with working Networking (Ethernet and WiFi) with Ruby/Rails. Information collected from various forum posts, blog posts, etc. Attribution added where I could remember. Using a Windows 8.1 machine, please provide comments for update regarding Mac/Linux tutorial translations (for the most part it shouldn't matter except for how you write ISOs to microSD cards).

Note: Relatively new at this level of Linux usage, if there are better ways to do something please mention in comments so I can update
