What are the best Git commands for new codebases?

Start with `git shortlog -sn --no-merges --since="6 months ago"` for contributors, `git log --oneline -20` for recent changes, and the file churn pipe for hotspots.

How do I find the history of a renamed file in Git?

Use `git log -p --follow -- path/to/file`—the --follow flag tracks renames smoothly.

Does Git history really speed up onboarding?

Absolutely—five minutes of commands give context that weeks of reading can't match, revealing why code exists as-is.
