I am not really impressed by your searching attempts Spectre!
Really, the most simple search query will give you a guide. Not only on google but also on the BI forums and here.

And not only that, I already pointed you to the guide before in another dedicated server thread
you made. Next time I feel you make fun of our forum rules they will be applied upon your account.
