Explanation
I'm sure there are plenty of other tutorials on how to do this and I'm sure nearly everyone knows how to set one up but some people do not. This may not be the best tutorial but I would just like to help any new people to the community. I will be using the flux files many people currently use. If you have any issues then please comment below and I will help you out. I am using windows 10 in this tutorial and it will be similar to other windows which you may be using.
