Updated: November 10, 2026

1. [Installing Tools: Homebrew and apt](https://www.ask-codey.com/lessons/bash-installing-tools) (Apprentice): A package manager is an app store you type to; on Ubuntu it's apt, which needs sudo to install, and on a Mac it's Homebrew's brew, which doesn't, and both search, install, update and remove tools by name.
2. [Your Dotfiles: A Setup You Can Carry](https://www.ask-codey.com/lessons/bash-dotfiles) (Journeyman): Dotfiles are the hidden settings files that make a shell yours; keep your own in a ~/dotfiles folder, link each one into place with ln -s, and keep the folder in Git if you use it, and a new computer is set up like your old one in a minute.
