The first thing you must do in order to setup your Snickerdoodle SD card is to pull down a disk imager utility such as win32 Disk Imager.
The next step is to pull down the Snickerdoodle Ubuntu 16.04 SD Card Image for the correct Snickerdoodle version. Once you unzip the image then copy it onto a blank SD card by use of the win32 Disk Imager by selecting the .img file and clicking "Write."
Once the image is finished writing you should be able to browse to the boot sector of the SD card via windows explorer and see the below files. Explaining what all of these files are is beyond the scope of this tutorial. However, all you need to know is that in order to boot with your .bit file loaded you must copy the .bit file into this directory and rename it to system.bit
Remember that the actual blink .bit file was located at the below directory: D:\craftDrones\firmware\blink\blink.runs\impl_1\design_1_wrapper.bit and that it needs to be copied to the boot sector as shown below.
Once the design_1_wrapper.bit file has been copied then rename it to system.bit in order for the boot files to recognize it.
