README.md

Assumptions

1. You installed rbenv and ruby-build via homebrew.
2. (Optional) You are listening to Ke$ha.

Simple Upgrade

1. Open a terminal.
2. curl https://gist.githubusercontent.com/prsimp/4567288/raw/upgrade_it.sh | sh
3. Drink some coffee or do something while Ruby compiles.
4. Profit!

What the heck is this doing?

1. Updates your homebrew formulae
2. Upgrades ruby-build
3. Installs ruby 2.1.1 and sets it as your default global Ruby (aren't we presumptious!)
4. Installs the bundler and rails gems globally.
