If you are using a Mac, install Homebrew and then run brew update && brew upgrade .
2. If you are on Linux or Windows, follow the instructions here to get Node installed: https://nodejs.org/en/download/package-manager/. Then run npm install -g yarn . This will also give you Yarn globally on your system so that it can be used in other projects without having to re-install it each time (which is what well do later)
