Breastfeeding help


So I am not a ftm, but I was unable to successfully breastfeed my first child. I would really like to attempt it with my second baby, but am having difficulty already. I put her to my breast, but not sure how to get her to feed. All positions just seem awkward, and coordinating everything seems to not be working. Anyone have any helpful hints on how they got off to a successful start? Thanks in advance!!
