I used Zola for a while, but at the end of the day there wasnt enough themes available that fit what I was looking for. I ended up messing with the templating engine to get what I needed.
I suggest OP choose Hugo over Zola, in the hopes that they find a theme that suits them best and for the most part prevents them from having to touch templating to begin with.
~/repo for code I write and ~/src for code I didnt.
