How/where do I put email list signup (using MailChimp)

Hi,
Setting up new site using Minamaze; and have signed up with MailChimp to create a signup for email list. How do I place this code for the sign up form on Minamaze theme? I am thinking of placing in one of the 3 content areas, but don’t know how to do it so it shows up correctly.

Thanks in advance!
