Transitioning to Crib

Let the fun begin! Transitioning a baby to a crib when she does not like sleeping laying flat is not so much fun. Ever since we brought her home, she hated the bassinet! She will play in the crib and pack n' play but wants nothing to do with sleeping in them. I just fed her and rocked her to sleep and she is now sleeping in her crib. Any suggestions on how to make this transition smooth?
