+Project demos help developers evaluate software before installing, deploying, or integrating it. They can include static previews, hosted examples, sample data, screenshots, or guided workflows that show the main behavior of a project. A useful project demo makes the project easier to understand by showing what it does, what problem it solves, and how someone can try it safely.
