How do I register an ens name?

Could you please elaborate on the process of registering an ENS name? I'm new to this and would appreciate a step-by-step guide. Is there a specific website or platform I should be using? Are there any requirements or prerequisites I need to fulfill before I can register? Additionally, are there any fees associated with the registration process? And finally, how long does it typically take to successfully register an ENS name? I'm eager to get started and would like to have a clear understanding of the entire process before proceeding.
