How to add social services to your site

What's the best way of adding social media icons or 'sharing functionality to your website? It is really as simple as signing up with either AddThis or ShareThis, choosing which buttons you want to display, then copying and pasting the embed code back into your Tank site: and you've enabled clean, simple social features on your site.

Please note

After you configure and theme your sharing buttons you need to copy the code generated and paste this in the Config / Tracking & Code screen in the Header Code variable over in your Tank site.
