canningusa.com is my favorite canning guide. Hot water bath (I'm not that good at descriptions, so someone else may need to chime in) Basically, you put a big pot of water on the stove, make sure the water in the pot is over the top of the canning jars by an inch, the cans also need to be lifted up by a rack or something so that water can go underneath the cans as well. Bring the water to the right temp and let it go for whatever time alloted.
Ok, that was a horrible description!
