Version control records how a project changes. Git can help a new programmer create checkpoints, inspect edits, and recover from mistakes. GitHub hosts repositories and collaboration features.
Inspect before saving
Check repository status and review a diff to understand which files changed. Add only the files needed for one focused change.
Write useful commits
A commit message should describe the change. Small, coherent commits make project history easier to review than one large snapshot with no explanation.
Share a clear repository
Add a README with the project purpose, setup steps, and how to run it. Before publishing, remove passwords, tokens, private data, and machine-specific files.
Branches and pull requests support review, but even a solo learner can benefit from a clean history and instructions another person can follow.
