1) Log in and click on the "Advertise" tab
2) Copy the script text to the left of the banner you would like to display on your site. Keep in mind you want to make sure the banner isn't larger than the area on the homepage you plan to place it. Otherwise it will get partially cut off. This may take some trial and error.
