If you want to make your social profile visible on your site, then you have the most popular social networks available for display. Just type the name of the social network  and provide the link to your profile, and the respective icon will be shown in the social icons widget. The following social networks automatically embed  their icons: Facebook, Twitter, Google+, Yahoo, Dribbble, Linkedin, Vimeo, Tumblr, Delicious, Flickr, Youtube, Instagram and Pinterest.  

Other social networks will require you to upload a dedicated icon with  the possibility to add a hover effect image as well.
