You can't just browse the raw HTML files of the site. The links wont work, and it wont have a proper header or footer. If you want to run this website locally, you should install Flask and run the website as follows.

pip install Flask cachelib
python lispy.py

You can specify port via $PORT.

env PORT=5000 python lispy.py

This will serve the site locally at http://127.0.0.1:5000/. You can browse it from there.
