Under the WP Widgets page, drag and drop the SliderPlus Slideshow widget to the desired widget area or sidebar or whatever your theme calls it.
All being well, the Slideshow should appear in the sidebar when you load the page.
Note: The eagle-eyed will notice in this example the content is somewhat squished out. SliderPlus Slideshows will scale their dimensions, but not the text size (otherwise it could get tiny!). So if you plan to use a Slideshow in a smaller area, it’s better off to create it specifically for that area’s dimensions.
