Hey Jay,
the Social Media Widget works as follows: please visit “Appearance -> Widgets” admin area, and drag the “Social Media Widget” from the left hand side into the “Footer” widget area on the right hand side. Once it is there, you can expand it and set the URLs for the social services you wish to display (e.g. if you need a Facebook icon, you need to paste your FB page’s URL into the “Facebook URL” field, etc).
Unfortunately, there’s no Behance icon available in the widget yet, but I’ve prepared an update for you that includes this icon as well. Please download this archive, unzip it, and upload the resulting file into the following folder: /wp-plugins/social-media-widget, replacing the existing file. Please also download this archive, unzip it, and upload all contents into the following folder: /wp-content/themes/Kanso/includes/font-awesome/, replacing the existing files and folders.
Sincerely,
Andrii / Satori Studio
