First, you'll need an account. Hit the DigitalOcean home page and click that SIGN UP button.
You'll want to pick a good password here, since access to this account gives root access to the servers you host under it.
Next, check your e-mail for a confirmation message from DigitalOcean, and click the confirmation link inside.
You should then be asked to provide a credit card number to pay for the account.
