Key ideas in Git: Version Control for Everyone
- Git captures the state of the whole project, not just a list of edits
- Git acts as a reliable record of progress over time
- A commit is a fixed point in time
- Commits are permanent and don't change even if you edit the files later
- Git's role as a high-fidelity record keeper
- The definition and permanence of a commit
- The repository (repo) is the hidden folder where all history lives
- The repo is distinct from the single version of files you see on your screen
- Git does not auto-save; the user must trigger a commit
- Committing at meaningful milestones creates a better history
- The purpose of the repository as a container
- Commits act as 'safety' points you can jump back to
- Experimental changes can be discarded without losing the original working state
- The learner's agency in creating history
- The psychological safety provided by snapshots
- Every Git commit is assigned a unique SHA-1 hash
You've tried the other tabs
Thirty open tabs. Four facts you actually kept.

One answer, then back to scrolling.
Eight weeks. You meant to finish. You didn't.
Tomo gives Git: Version Control for Everyone the Duolingo treatment: levels, streaks, and quick quizzes that test what you just learned. That game loop is what the tabs above never had, so it's the one you actually finish.
