There are multiple steps. I will go from the start to the end. If you decide on having multiple domains?, then you would find these steps as simpler to do as you get practice. If you are only intending on one or two domains, then you won’t need to worry about these steps beyond doing what you need to do. I will try to be detailed as much as possible, but considering I had used my registrar, and host since 2002, some things might have changed slightly.
