Choosing a theme

It was not so easy to find the appropriate theme for this short experiment:

• The learn theme is great, but I was not able to embed HTML content that uses requirejs (e.g. Jupyter widgets or interactive tables).
• The ananke theme has no such issue, but I was missing the navigation menu.
• The hugo-book theme looks great, but I wanted a button to go to the next chapter.
• The hugo-theme-techdoc works super well! It even has the edit on GitHub link.
