Trying to sleep train (need advice)

I want to start having my 12 month old sleep in her own crib, we've been bed sharing (no shaming, please) and she does rely on nursing to get to sleep, but we're slowly trying to wean on that too. My question is, is can i start sleep training and stopping the night nursing all together or what would you suggest would be the easiest? This momma needs all the help! Also methods of sleep training too please!
