Transition to Crib

I need advice getting my baby to sleep in her crib! She's 8 months old and currently sleeps with me. Personally, I don't like co sleeping and it makes me anxious, but it was what I had to do at the time due to certain circumstances. Now however she has a crib and her own room I'm just not sure how to get her to sleep in it. Everytime I put her in the crib she screams. It makes me feel so terrible, but I need her to get used to it and start sleeping in her own room. We have another baby due in a few months and can't have her in our bed when the new baby arrives. No one will get any sleep if she is.
