It's amazing that in 2018 we keep building new CMSs. Human curiosity is without limits. I'm genuinely amazed about this. And seeing a CMS built with Go is refreshing.

I have to say though, the "What doesn't it do?" section seems like an extension of the "What does it do?" section. A "What doesn't it do?" should list what the CMS actually doesn't do instead of listing things nobody wants anyway. Who wants "hundreds of complicated back-end screens"? No-one. So no need to say that the CMS doesn't do that.
