I’m using the really nice minimal Minos theme. By default, it does not include a one-liner description. After checking the docs, there wasn’t any setting available in config.toml. After some research, I found it’s possible to overide the theme’s header with a custom one. Here’s the process I performed: in the themes/hugo-theme-minos folder, find the header currently being used for the site in your site folder, find the layouts folder (which is likely empty).
