Prerequisites

1. Run all of the OS updates that are available
2. Install Homebrew and tap the casks we'll need (brew tap homebrew/cask-fonts, brew tap homebrew/cask-versions)

Shell setup

• install ZSH - brew install zsh
• set ZSH as the default shell by 1) adding the output of which zsh to /etc/shells and 2) changing the default shell with chsh -s $(which zsh)
• add autocompletion to ZSH brew install zsh-autosuggestions (be sure to follow the instructions output by brew to update your ~/.zshrc)
• later, after installing Node install a cool command prompt like spaceship (more here) - npm install -g spaceship-prompt

Chromebook Setup Options

Option 1: Stay in Chrome OS

If you're writing bare-bones javascript for the browser, creating Chrome Apps and Extensions, or using remote coding apps like cloud9, Koding, or Nitrous, you may not need to install Ubuntu. Some tutorials can be done entirely within the browser. The tradeoff is that you won't have a full-featured command line, and you may hit a point where you can't install something that you need.

To start coding within Chrome OS, install Text or Caret as a text editor. (Text stores files in Google Docs and Caret stores the files locally on your machine, which may help you choose.) After that, you're good to go, since Chromebooks come with a browser installed.

Switch from RVM to rbenv:

Get Rid of RVM if it's installed:

rvm implode

Cleanup your .bash_profile/.bashrc/.zshrc file to remove RVM from the path:

You should have something like this left from RVM. Delete it from the file. ``[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm"```
