This site seems much more like an some of the awesome- repositories on github than a guide. Although it does give some extra information on the packages. To not make it took negative. I personally use Chezmoi, which I've been super happy with. The ability to maintain files in a central repository and then pull them into the file system on an update is quite nice. You can handle merge conflicts and whatnot between you…
I guess I don’t quite get it. It’s not a ton of work for me to manage things with git, symlinks, and a makefile. Clearly chezmoi adds some polish and maybe additional features, but I don’t see how that outweighs learning a custom tool for this one thing.
My complex use case is that I use all three of the main OS' and so there are some dotfiles for desktop apps that live in Windows' home directory and some that live in WSL, so having something manage that for me is pretty nice.
