SliderBrowser Info Environment
this should be automatic. For instance, if you add two Content blocks (one under the other) to the Main area, once you publish the page, you should automatically get something like the demo: every block you've added should become a slide, and the top navigation bar and the arrows should let you scroll to the following slide.
You don't need to code or install anything else.
If you post a link to your site, I can have a look.
Hope this helps,
