This program will generate a premium minecraft username and password for you. So that you don’t have to buy the game yourself.
It actually just grabs a random one from the minecraft server so if you behave normally the person who owns that account won’t even notice that you are using it.
As you can see in the image below it is a very easy and clean program to use, so I don’t think there are any instructions needed here.
