Clone repository, then from ~, run

for x in `ls .dotfiles -A`; do rm $x; ln -s .dotfiles/$x $x; done

to symlink all the files into place (may print error messages if you don't already have the files in ~).

If you want configurations to be specific to computer, consider using uname -n to distinguish.

You'll want:

• karabiner-elements
• hammerspoon
• 1password
• iTerm2 (will require xcode developer tools)
• this repo (if you want to have the remote attached properly, will require either old ssh keys or that you upload a new one to GitHub)
• chrome + firefox
• homebrew

The rest you can mostly figure out on the fly.
