Install Homebrew without sudo

Confirm the directory you want to run it from. I ran this from within my home folder.

Install

mkdir homebrew && curl -L https://github.com/Homebrew/brew/tarball/master | tar xz --strip 1 -C homebrew

OR

git clone https://github.com/Homebrew/brew homebrew

Configure Environment

eval "$(homebrew/bin/brew shellenv)"
brew update --force --quiet
chmod -R go-w "$(brew --prefix)/share/zsh"
