Demos should be around 3 minutes long.

Things your demo should include:

• Your team/project name
• Which track you worked on (Sustainability, Health, Economics)
• The challenges your project is responding to
• How your project addresses the challenge
• What technologies (languages, platforms, APIs, hardware, sponsored tools, etc.) you used
• What you learned from this event
• What problems you ran into and how you solved them
• A video demo ≤ 3 minutes long showcasing the features of your project
• Anything else you think is important that your project will be incomplete without

The best demos are the ones that engage the judges. Make sure to include a link where judges can try out your app/project/hack if applicable while you explain to them how it works in your video.
