If a line starts with '#', GitHub will show the line as a heading. That may be a GitHub bug (I'm not sure what the Markdown spec says about this), but anyway, let's rewrap the text so that GitHub shows the text as intended.

Intel(R) Minnowboard Max
MinnowBoard MAX is an open hardware embedded board designed with the Intel(R) Atom(TM) E38xx series SOC (Fromerly Bay Trail).
For product overview and faq see http://www.minnowboard.org/faq-minnowboard-max/

Supported Firmware
mraa has only been tested with 64 bit firmware version 0.73 or later.
Interface notes
The low speed I/O connector supported as per table below. This assumes default BIOS settings, as they are not dynamcially detected If any changes are mode (Device Manager -> System Setup -> South Cluster -> LPSS & CSS) them mraa calls will not behave as expected.
Documentation shows i2c on bus #5, ACPI shows it on bus #6, but driver uses bus #7.
SPI operation is not currently supported
