Everyday Git
Stop worrying about breaking your code or losing past work. Learn the core mental model of snapshots, experiment fearlessly with branches, and confidently undo mistakes.
Like Duolingo, but for Everyday Git. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
A short one: 11 levels across 2 sections, about 22 minutes end to end, roughly 4 days at five minutes a day. It moves through Building the Safety Net and Branching and Recovery. It starts from scratch.

Key ideas in Everyday Git
- Git records changes as a series of point-in-time snapshots inside a single repository folder
- You do not need multiple copies of your project folder (like 'project_final_v2') to preserve previous work in Git
- Git lets you switch between past versions within the exact same workspace
- The staging area lets you selectively pick which modified files to include in your next snapshot
- Running git add on a specific file stages it while leaving other modified files untouched in your working directory
- Only files added to the staging area will be bundled into the next commit
- Every Git commit records who made it (author name and email) and when (timestamp)
- Every commit includes an explanatory commit message supplied by the author
- Once recorded, this metadata and the file snapshot form an immutable checkpoint in your project's history
- Good commit messages explain the 'why' (the reason or intent behind the change), not just the 'what'
- Git's diff already displays which specific lines changed, so repeating line numbers in the message adds little value
- In a Git diff, lines starting with '-' show what was removed
- Lines starting with '+' show what was added in their place
- `git diff` lets you review unstaged line-by-line edits before committing them
- `git log` lists commits in reverse chronological order
- The newest snapshot appears at the very top of the output
You've tried the other tabs
Thirty open tabs. Four facts you actually kept.
You watched. You nodded. By Sunday it was gone.
One answer, then back to scrolling.
Eight weeks. You meant to finish. You didn't.
Tomo gives Everyday Git 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.
