I use this GitHub Pages site to host my presentations.

The canonical domain name for this site is prberg.com, but you can also access it via paulrberg.github.io.

GitHub Pages uses Jekyll for building websites from repository contents. By default, Jekyll excludes certain files from the build process, such as files and folders that start with a dot (.) or an underscore (_).

For guidance on how to exclude more files, see my conversation with ChatGPT.
