How do I get my twelve month old to sleep in her crib for naps?

I know I’ve formed a terrible sleep association for her by letting her nap in my arms every day since she was born, but I’ve got to get her napping in her crib now as I’m planning to go back to work soon. She sleeps in her crib at night when I put her in already asleep, but when I try to put her in her crib already asleep for naps she wakes up right away and screams bloody murder😩

Any ideas? Any suggestions on sleep training methods to get her going to sleep in her crib completely on her own instead of having to be asleep when I put her in?
