Valve clearance for dummies?

[s1500@comcast.net]

Looking at both the Haynes and Bentley manual, I'm still unclear on how to do 
valve clearence adjustments.  I know how to slacken & stick in the proper 
feelers, just don't know which one to do when the engine is cranked to where. 
I'm assuming valve #1 is at the front of the car. 

When they mean IN, does it mean the valve is up(closed) or down?
