Overview

Git is a distributed version control system tracking snapshots (commits).
GitHub hosts remote repositories enabling collaboration via pull requests.

Core Commands

git init — create repo
git status — view changes
git add . — stage
git commit -m 'msg' — snapshot
git log --oneline --graph — history
git branch / git switch — navigate branches
git merge / git rebase — integrate
git push / pull / fetch — sync remotes

Branch Model

Feature branches isolate work.
Main stays deployable.
Use pull requests for review & CI.

Minimal Example

git init
echo 'hello' > README.md
git add README.md
git commit -m 'init'
git remote add origin <url>
git push -u origin main
