How to play in which position?

Im sorry as Im sure there are many topics on this subject, but I couldnt find what Im looking for using the search.

Could someone either try to explain, or atleast direct me to an explanation on how to play different positions in poker. I know that the best to be in is on the button. What strategy change should one use in different positions? And if this is a stupid question, dont be afraid to let me know. I can see that it is a little broad and I just can't get out specifically what Im looking for.
