For starting out, I would suggest looking into what each palm line means. It's better to start of slow then jumping in. There are many lines that can be read on a palm, but to begin with I would start with the four major lines, Heart, Life, fate and head. Once you have a good understanding of them and there varietys, I would look into more detailed palmistry. A good website for starting out is this article on Wikihow.
