# Welcome! If you're new to this sort of stuff or coming back to it after mobile/backend development, here is a recommended workflow: 1. Install VS Code. 2. Install the Prettier and ESLint extensions. 3. Enable the VS Code setting to format on save. 4. Install node on your machine `brew install node@20`. Our package manager, `yarn` comes with it. That's it. Enjoy coding! ## Yarn Note that we use Yarn classic ``` $ yarn --version 1.22.21 ``` You should be seeing a 1.xx.xx version, otherwise your `yarn install` will fail.
