That depends on what editor you're using. It looks like you're using the VisualEditor (I use source mode myself), in which case you can click on "Insert" (below the buttons for Bold and Italics) and then select "Infobox." Select the infobox you'd like from the list, fill it out, and hit "Apply changes." That should do it.
