Notes on using Homebrew Zsh as default login shell

Homebrew Zsh on Mac

1. Install Zsh with Homebrew
	brew install zsh

2. Add "/usr/local/bin/zsh" to "/etc/shells" file
	sudo vim /etc/shells

3. Change to default login shell
	chsh -s /usr/local/bin/zsh $USER

4. Make sure new version of Zsh is in active
	echo $SHELL 		(should see "/usr/local/bin/zsh")
	echo $ZSH_VERSION 	(should see "5.0.2" instead of "4.3.11" bullt-in in OS X 10.8)

5. Create "/usr/local/share/zsh/site-functions" directory to match with what's in "echo $FPATH" output

6. Support homebrew completion with the command
	ln -s /usr/local/Library/Contributions/brew_zsh_completion.zsh /usr/local/share/zsh/site-functions/_brew
