There's a few special files in the hierarchy.

• bin/: Anything in bin/ will get added to your $PATH and be made available everywhere.
• Brewfile: This is a list of applications for Homebrew Cask to install: things like Chrome and 1Password and Adium and stuff.
• topic/*.fish: Any files ending in .fish get loaded into your environment.
• topic/path.fish: Any file named path.fish is loaded first and is expected to setup $PATH or similar.
• topic/completion.fish: Any file named completion.fish is loaded last and is expected to setup autocomplete.
• topic/install.sh: Any file named install.sh is executed when you run script/install. To avoid being loaded automatically, its extension is .sh, not .fish.
• topic/*.symlink: Any file ending in *.symlink gets symlinked into your $HOME. This is so you can keep all of those versioned in your dotfiles but still keep those autoloaded files in your home directory. These get symlinked in when you run script/bootstrap.

Run this:

git clone https://github.com/jpvanhal/dotfiles.git ~/.dotfiles
cd ~/.dotfiles
script/bootstrap

This will symlink the appropriate files in .dotfiles to your home directory. Everything is configured and tweaked within ~/.dotfiles.

The main file you'll want to change right off the bat is fish/fishrc.symlink, which sets up a few paths that'll be different on your particular machine.

dot is a simple script that installs some dependencies, sets sane macOS defaults, and so on. Tweak this script, and occasionally run dot from time to time to keep your environment fresh and up-to-date. You can find this script in bin/.
