It's an additional address on your existing account, not a separate account, and your @me.com address will be unaffected and will continue to function exactly as before. You don't have to do anything to get email@example.com address; it will simply deliver into the same inbox alongside your @me.com address.

Copied from the support article you arrived here from:
"Note: No matter which address you choose to send email from, you will continue to receive all email sent to your @me.com, @mac.com, or @icloud.com email addresses directly in your iCloud inbox."
