A.B.
As for myself I chose what I wanted to grow and then went to ask.com and asked "How do you grow cantelope/green beans/etc".
Produce that's more acidic (like tomatoes) you can can by boiling but most other stuff you'll need to get a pressure canner to avoid them getting botulism and stuff.
Berries and peppers you can freeze to use anytime in the next year.
It is a lot of work but you can show off to your friends your awesome garden!
