Trimmer potentiometer?

I have a problem with my voltage regulator LM317T that I use for the power supply I built. the volt regulator gets hot when I connect the device to it. Someone in this forum suggested using a 5K ohm trimmer pot and a heatsink. Setting up the hetsink was easy but how i should put the 5K ohm pot in my circuit? i.e. where the three pins that comes out of the potentiometer should be connect to?

You connect one end lead of the variable resistor to the Vadj lead of the LM317T, then you connect both the center lead and the opposite end lead to ground. You will be adjusting the output of the LM317T.

Added info: Is your regulator mounted on a heatsink for a TO-220 configuration? It's rated for 1 amp without a heatsink and 1.5 amps with a heatsink. You must be pulling close to 1 amp if it is getting hot. Check out this link below
