Git
Never lose
your work
Beginner
What's inside
Seven chapters, from first commit to published project.
01
Why version control exists
What Git actually does, why it isn't a backup, and the difference between Git and GitHub in one page.
02
Set up once, calmly
Install, tell Git who you are, and create your first repository — on Mac or Windows, side by side.
03
The everyday loop
Status, add, commit. The three commands you'll run hundreds of times, and how to write a message you'll thank yourself for.
04
History and undo
Read your own history, recover a deleted file, and back out of a mistake without panic.
05
Branches without fear
Try an idea safely, merge it back, and handle a conflict the first time you meet one.
06
Putting CheckMate on GitHub
Push a real project online, keep secrets out of it, and understand what everyone else can see.
Look inside
Three real pages from the 23-page PDF.
Rendered straight from the file you'll download — an explanation, a worked step, and a page from the build. No mock-ups, no stock screenshots of someone else's screen.
CheckMate — the small task tracker every SecondNature code guide builds — is what these pages are working towards. Foundations gets it running; Level 2 makes it real. See the rest of the collection →
Who it's for
People who've already lost work once.
Git is the safety net every developer takes for granted and no one explains. This guide teaches it as a habit — a few commands a day — rather than a manual to memorize.
Useful even if you never write code: writers, analysts, and anyone who versions files by renaming them.
Questions
Before you buy
Do I need the earlier guides?
No. Git works with any files at all — code, documents, spreadsheets. You can start here.
Do I need a GitHub account?
Only for chapter 6, and the free account is all you need. Everything before that runs on your own computer.
What if I break something?
Chapter 4 is entirely about undoing safely, including recovering files you thought were gone.
What do I get after checkout?
An instant download link for a clean, print-friendly PDF. Yours to keep, on any device or printed.
