Ok this is my first tutorial.
First thing to do is spawn a computer. I use the LaptopBig_Download one. I think it works on one other computer but i never tried.
Then set all nodes as shown in the picture. And connect them the same way.

Ok for the second part. Set the nodes as showed in picture again and link them.

And about not necessary part, you must keep the 12 second delay. The other thing is a dialog that nomad says at the start of the download.
Well thats about it. If any of you find a way to upgrade it or of the tutorial doesn't work PM me.
