In a previous post I showed you how to put adsense into your website manually, however this video shows you how to install a plugin that will help you manage your advertising needs. Of course if you use the Socrates theme you will have easy options to place the code in without using any plugins.
I would rather put the Adsense code into the website myself. Here’s another video that shows you how. http://letsbuildwebsites.com/how-to-put-adsense-ads-inline-with-your-wordpress-posts/
