Thank you for your suggestion. I will update the examples on the landing page very soon.
By the way, I've already added a download page at https://m-creativelab.github.io/jsar-runtime/download.html. There, you can download the macOS application which allows you to open supported HTML files. You can also find sample HTML files here: https://github.com/M-CreativeLab/jsar-runtime/tree/main/fixt....
It would also be good to have a link to examples very high up on the front page.
