Where can I set options for the Flexslider? Can I?

I have included a Flexslider in one of my pages. It works fine, but I want to set the speed and size? Can I do this?

I have browsed this forum and read the documentation. The forum has nothing on it as far as I can tell.
The documentation has four bullitpoint steps. I get the first three, but noth the fourth. It reads “Select the FlexSlider group on the WP page.” I can not find ‘the Flexslider Group” anywhere. What am I missing?
