This document discusses developing multi-modal skills for Amazon Alexa with both voice and display capabilities. It provides 7 tips for using the display effectively: 1) avoid long texts, 2) do not repeat what is said in voice, 3) use background images, 4) include images and videos, 5) use lists and hints, 6) consider different display sizes, and 7) prioritize voice-first interactions so the skill works without a display.
