Why not some Rust in your website stack? At least use Zola instead of Hugo… I know I’m in the my, but I believe in using the language fully if you’re going to provide a learning resource for said langauge.
Use right tools! don't be a die hard fan of any language. However, I used many tech stacks including Hexo navy theme, Docusaurus, Docsy but ended up creating my own setup with Hugo. If you can see, in the project it's more or html/css that can be used with any builder.
I guess I'm of the wrong mindset that when trying to teach a language, it helps to do all the things in said language, because then you've got lots of fodder to write about and explain other people's code, pointing at your own use case as examples.
As I said, I'm clearly in the weird minority on this one and should have kept my damn trap shut. We are all free to make our own choices.
I suppose too I was coloured by my hatred of Hugo. :)
