How to curve a golf ball while putting?

QUESTION: I recently have gotten into golfing and one of the things I was confused about is left-right / right-left curving of the golf ball in putting. Instead of just hitting the golf ball straight towards the cup, how do I put spin on the ball and curve it? Any video that you might have found online would be the most helpful, but you can try to convey the techniques in words to. Thank you very much. ANSWER:

You don't put spin on it, You put it on a slope to get it to curve. The curving is more like compensating for wind and slope. If you have the option to putt it straight in, putt it straight in.
