Of all of the Hugo themes I have encountered, I have never seen anything as dogfed as this. Comes with a complete documentation.
ironically it is not even found in themes.gohugo.io
It's basically freemium.
Plus it's got additonal free theme components you can add like image compression, gallery, and a #@&3ng monero miner!
Indeed that's the most complete theme ever written for Hugo, still muted by Hugo team because of the optional miner module included and their stupid policy to allow only github or gitlab hosted themes! They removed it from their gallery although they allow others that grabbed after-dark's source...
