There is no need to look up this procedure.
With the bike sitting there turned off, push the clutch lever out from the handlebar as far as it will go. Don't use great force, a pinkie finger will do.
Using same pinkie finger, lightly pull the clutch lever towards the handlebar. Use no great force. Perhaps use about the force it takes to push down a key on your computer keyboard. You are not trying to pull it in ... only trying to see if the clutch lever is capable of wiggling in and out a little bit.
If you feel a little bit of looseness, perhaps 5 - 10 mm of sloppy movement at the outer end of the clutch lever before it starts actually pulling on the cable, it's good.
If it is tight as a drum with no looseness and the cable starts pulling the moment the clutch lever moves, it's too tight.
Adjusting it is almost as easy. Find where the cable attaches to the lever. It's clearly visible. Note that where the cable is attached, there is a threaded adjuster. Adjust it. (You may have to loosen a small knurled locking nut first.) No tools needed unless someone has reefed on the locknut - in which case, any set of pliers can be used to get it loose.
