1. As of 5/7/24, the README.md says:

For an updated list of supported platforms, visit:

http://xinu.mscs.mu.edu/List_of_supported_platforms

That link does not work. However, this more unwieldy (with intervening index.php) url works:

https://xinu.cs.mu.edu/index.php/List_of_supported_platforms

2. Either fix README.md or fix the website so that the link in README.md works.
