Our social media components for the Farmers Market site are limited to links in the footer that will take a site visitor to whichever social media pages that we make available. We're using the On the Web module.
Once you configure this module at: /admin/config/services/on_the_web, you will place the Social Media Icons block on any layouts where you would like this to appear. For our site, we started with the Home page and the Default layout. As we build the site and add additional layouts, we may need to add this block again.
