Couponing

I have decided I want to start couponing. Not on random things, but on the things we actually need. Toilet paper, diapers, wipes, formula, paper towels, ect. But I have NO clue where to start. Being that we are on one income and I stay at home we need to save as much money a a possible. I have looked in the paper, online, and on Pinterest which has helped a lot. I a lot of things we buy are Kroger brand because Chad works for the company we get an extra percentage off of the items. But if we can save more money on the name brands, I will do so. I am just having a hard time starting. If anyone could help me or give me any tips that would be awesome!
