@Nono I used the Hugo exporter plugin for WordPress. Worked fairly well but I had to fix a lot of image tags. I originally wanted to use Jekyll because I had experience with it, but that plugin didn't work with my WordPress version and jekyll's console-based export required a Ruby version I couldn't get easily on the old version of Debian I was using. Happy I went with Hugo though, it was pretty easy to pick up!
