iTerm2, zsh shell, PowerLevel9k theme

1. Install the terminal iTerm2 here or through homebrew using brew cask install iterm2
2. Then install the shell Zsh (a alternative to bash) using brew install zsh
3. Change the default shell to Zsh rather than bash, run the change shell command in your terminal: chsh -s /bin/zsh
4. Download freeCodeCamp powerlevel9k theme: wget https://raw.githubusercontent.com/ryanwhocodes/powerlevel9k-freeCodeCamp/master/freeCodeCamp.itermcolors
5. Download Nerd Fonts: brew tap caskroom/fonts; brew cask install font-hack-nerd-font
6. open iTerm2: open /Applications/iTerm2.app
7. set a colour scheme: iTerm -> Preferences -> Profiles -> Colors -> Color Presets -> Import
8. Configure iTerm2 with Nerd Fonts: iTerm2 -> Preferences -> Profiles -> Text -> Font -> Change Font
9. Also check the box for Use a different font for non-ASCII text and select the font again.
10. install the Powerleve9k: git clone https://github.com/bhilburn/powerlevel9k.git ~/powerlevel9k
11. load powerlevel9k when Zsh starts: echo 'source ~/powerlevel9k/powerlevel9k.zsh-theme' >> ~/.zshrc
12. You need to tell Powerlevel9k to use the Nerd Fonts in your ~/.zshrc: echo "POWERLEVEL9K_MODE='nerdfont-complete'" >> ~/.zshrc
13. Configure prompt elements and layout and create custom prompt segments: check my .zshrc gist
