CB550 Clutch Adjustment

Does anyone have a good link to a step by step or a video for a clutch adjustment for a CB550 (1978)? I have the manual, and checked searching, but the manual kind of offers a poor explanation for it.

.
there is a screw and round nut on the cliutch bracket in the bars . . loosen the nut, then adjust the screw until you can pull the lever around 1/2" before it dstarts to get a little hard to pull.
