How do I feature an article on the home page?

Open the article in the editor, go to Config, and set Feature on Home to Yes. A Live Now block set to Automatic can then promote it. Leave Feature From and Feature Until empty to feature it for as long as the switch is on, or set them to give the feature a window, after which the hero moves on by itself. A live event or tonight's event still comes first; the article shows when nothing is on the air. To force one article to the top regardless, set the Live Now block's Feature to An article I choose and pick it there.
