How do you install a serpentine belt on a 1992 Silverado?

On the radiator cover, there is a sticker that shows the diagram of the belt routing.

I found it's easier to remove the fan cover and start on the bottom center then the part of the fan is not in the way then go down around the right pulley and set it on the top right pulley then the same on the left the top center you may meed help so you dont do what i did and get your finger smashed when getting it under the top pulley the tension pulley it gets pushed down to the left as you r looking at it and feel the pulleys and if there are groves the belts groves go there
