Content Dock Widget Area
Upon activating the Content Dock, a new widget area will be added to your WordPress admin under Appearance > Widgets labeledContent Dock. This is where you will be able to add anything that you want output. You will most likely want to use a Text widget, which will allow you to take advantage of shortcodes.
Content Dock Display
The Content Dock is visible on displays larger than 767px and will be hidden on any displays smaller than this. This is for numerous usability reasons, which mostly have to do with ensuring that your site’s primary content is always accessible and not completely hidden by the Extension and that the close button is not inaccessible.
