I will be documenting the only relevant bits of my dotfiles in the README.
The scope of it was to be as close as possible to the fish shell experience.
My .zshrc does not depend on oh-my-zsh or anything like that. Keep this in mind if you want to use that.
A note: the prompt is different from the fish prompt. This is on purpose. I love my prompt when it is customized and minimal.
If you are looking for a copycat of fish's prompt, you could always make it and export it to PS1.
You got a handy dandy install.sh for that.
