It just writes image to selected USB stick or SD card and creates "install" media.
Sry for coming back that late (*) - Yes, I think the tool can make it easier for some audience to bring the image file onto a media.
However frankly I thought in the beginning, that it would 'simplyfy' the process getting to a 'running' system, avoiding the "2 step" process, 1st having to get the image on e.g. USB pen, then booting that pen finally installing LE on the target device.
(*) I just gave it a try, when I wanted to get LE on a (tiny 2 GB) Transcend SSD which I attached via SATA in an ASROCk ION330HT
I PXE booted the ASRock with a Live Ubuntu, dl'ed the (64 bit) USB-SD creator.
But when using it, it didn't find any device.
So I attached an 2 GB USB pen too, writing LE there, dd'ing from /dev/sdb to /dev/sda, however when booting from sda just to find out, that it offers me to install LE to another media
