You'll find setup details in the theme's readme.txt file: Jetpack gives you access to the Featured Content module. You can then choose a featured-content tag in the Customizer's Featured Content section, and up to six posts with that tag will appear in the Featured Content area. Gazette isn't yet in the Wordpress.org repo but you'll find more basic setup info here: https://theme.wordpress.com/themes/gazette/
