Roslyn - Social Media Icons Setup
This theme uses the Simple Social Icons Plugin to display social media icons, which can be obtained here or by searching in Dashboard > Plugins > Add New.
In your Widgets page, drag the widget labeled “Simple Social Icons” into a widget area.
The demo displays them in the Primary Sidebar.
Configure the widget by choosing a title, icon size and color, and add the URLs to your various social profiles. Please note, if you add the Simple Social Icons widget to two widget areas, they must match on all settings.
Here is a screenshot of the settings used in the theme demo -
