Q: I want to give my mac pro to my daughter as a gift, how can I transfer the ownership of the apple ID?

I want to give my mac pro to my daughter as a gift, how can she sign in with her own of apple ID? I have try to reinstall the OS using the cmd+R, but it started again with my user ID. The mac is brand new, but I started with my ID and now we don't know how to fix it.
