This plugin implements 2 new shortcodes.
[widget name=”” classname=” instance=””] to use a widget per shortcode in the content area from a page/post.
name is the name of the widget, e.g. Calendar. 
classname is the name of the PHP Class that implement the widget. 
You can use name or classname.
So are [widget name=”Kalender” instance=”title=Hello,World!”] 
and [widget classname=”WP_Widget_Calendar” instance=”title=Hello,World!”] 
produce the same output.
instance are the attributs of the widget. e.g. title=Hello,World! so the complete shortcode is 
[widget name=”Calendar” instance=”title=Hello,World!”]
For the instance list of the WordPress builtin Widgets look at https://codex.wordpress.org/Function_Reference/the_widget 
For other Widgets look at the source code from the widget or ask the widget author.
[sidebar name=””] to use a sidebar (with all widgets) in the content area from a page/post.
name is the name of the sidebar e.g. Showcase Sidebar so the complete shortcode is 
[sidebar name=”Showcase Sidebar”]
For own css styling, the plugin wraps the widgets in < div id=”Widget_Name” class=”widget_shortcode”> and the sidebar in < div id=”Sidebar_Name” class=”sidebar_shortcode”>
