This theme has nine widget areas. One is for the blog sidebars, one is for the dashboard sidebar (IgnitionDeck Commerce feature), one is for the IgnitionDeck sidebar (used on ID archives pages) and six are for the footer. Go to Appearance > Widgets and you’ll see them. Also, remember that all shortcodes can be used as a widget.

To do this, just insert a text widget in any sidebar and paste the shortcode which you want. For example, this is how the online demo’s footer’s bottom second widget area is set up:

[krown_social twitter="#" facebook="#" linkedin="#" gplus="#"]
