Windows
- Prefer WSL2 if you want the closest experience to the Unix-based material in Missing Semester.
- PowerShell is useful and worth learning later, but this module assumes a Unix-like shell model first.
macOS and Linux
- Native Unix-like tools align directly with most examples in this module.
- Keep your shell config conservative at first; focus on repeatability and clarity.
