- _config.yml is the Jekyll frontmatter that defines the configuration for GitHub Pages.
- default.html adds a sidebar to every page by "default". This is the lowest configuration way of adding a sidebar I could find, without going full Jekyll.
- To ensure simplicity, I used the └─ character to depict subdirectories in the sidebar, otherwise we'd need to define the sitemap in HTML.
- Most of this was taken directly from this theme's github page https://github.com/pages-themes/minimal/blob/master/_layouts/default.html
