[tor-relays] Setting up a relay

Anyone that has a very specific guide available to setting up a relay? I was thinking of doing this since I'm a firm believer in anonymity, I use TOR myself so might as well help the network and I have decent internet connection that is quite unused most of the time (100 Mbps down/10Mbps up).

I was trying to follow up on that help section on the official site but it wasn't enough. There's a possibility the relay didn't work because of my router but I have opened the rights ports, tested by putting some limits and just testing some settings but not avail.
