Your first step is to google Dogie's Miner Setup Guides and go from there. Overall, it took about an hour to glean information and setup the first miner, then only about 5 minutes on the next.
It might be Sushi but I'm not sure he sells on Amazon. Either way whoever is listing them on Amazon keeps infringing on my copyright.
As mentioned many times before, if that individual is infringing on your so called copyright, contact Amazon and your local police. Grow up and stop whining like a little child. Most people have stopped purchasing bitmain over priced under supported products and are buying spondoolies offerings. When one in three power supplies catch fire in the s4's, I know what I'd prefer to buy from a safety standpoint.
