As posted above just do the Google search thing. Canning tomatoes is easy. If this is your first time and you are not sure you will be doing it again you don't have to buy a bunch of equipment. Any large pot will work for a simple hot water bath. Just need jars and lids. Only special tool I recomend is a set of "jar lifter" type tongs. I have done paste and sauce but not sure they are worth the effort but canned home grown tomatoes are. Wife and I used to can lots of stuff but now just tomatoes, peaches, apples and pears. Have done potatoes, corn, beans and even chicken.
