The Settings section allows you to add any site wide settings you would like. You can add an image upload setting for your site logo or a text box for the main headline on your homepage.

In this new version you have the ability to add different groups for different settings. So, if you created a new setting inside of the site group and it had a key of title you would then be able to reference that setting any where on your site by doing the following:

echo setting('site.title');

Or inside of any blade template like:

{{ setting('site.title') }}

So, now you can add all kinds of settings in Voyager and reference them in your application.
