My bad, last 2 commits referenced the wrong issue, rebased those commits but doesn't seem to disappear from here.

To expand on the "Add an overlay to the nim pkg in shell.nix to add the tools/ directory and compile dockhack." task, I would like to better create a nix flake which can be used to hold all the build commands for generating docs, testing, benchmarking, etc. I need to learn how they work since I have never used them though, so for the moment I will add this new tasks:

(Edit: moved the tasks to the main issue comment)

I don't know if it's possible to do those, but iirc I have seen stuff like nix build .#buildMyPkg, so I think it might be possible to achieve this. Edit: check the issue listed in the comment below for more info.

Actually I'm moving the nix flake task to it's own issue, #7

About customizing the html and css generation, that can be done later since it's not that important, closing the issue for now.
