How to transfer ens ownership?

How do I go about transferring the ownership of an ENS name? Could you please provide a step-by-step guide? I'm not very familiar with the process and would appreciate it if you could explain it in simple terms. Is there any specific documentation or resource that I could refer to for more detailed information? Also, are there any fees involved in the transfer process, and if so, how are they calculated? Thank you for your assistance.
