Posted link has virtually no description of what the project is.
Going to the root of the github repo has release notes and with the most detailed description as "HTML/CSS/JS Terminal" but burned into a PNG file.
Best description of the product is on "hyper.is" in an animated GIF form.
People working on project like this need to understand that without a reasonable textual description of their product, outlining basic features and benefits over other existing systems, that the uptake is going to be very, very low.
