[chezmoi] Which config files/directories should I add to my Chezmoi repository?

I recently started with Chezmoi to keep my ZSH configurations (among others) synchronized between my devices. So I've added the entire ~/.oh-my-zsh folder to Chezmoi, with the results I imagine many of you can guess: changes to the git hashes every time I update the system, omz update fatal errors and whatnot.

I now want to only synchronize the strictly necessary. What would that be, apart from the ~/.zshrc file and the ~/.oh-my-zsh/custom folder? Am I missing something (personal configurations, profiles) or is that it?
