lewagon/dotfiles ? reverse-engineered prompt

Build me a simple dotfiles setup for students so they can quickly configure a new Mac or Linux laptop for coding.

I want one easy install script that sets up their shell, Git, and VS Code in a clean, friendly way. Include sensible defaults for zsh, a few useful aliases, a good git config, and basic editor settings and keybindings that make everyday coding feel smoother. It should also include the small config files people usually want for Ruby and test output, plus anything needed so the setup feels consistent out of the box.

Keep it lightweight and easy to understand, since this is for beginners. Make the install process as hands off as possible, and if you need current setup details, look up the latest docs online.
