What is git

Git is a version control system — a timeline for your code. Every commit is a snapshot, and Git lets you navigate between them.

Run Through

Command	Purpose
git clone	Copy a remote repository locally.
git status	Check what’s changed.
git add	Stage changes for commit.
git commit	Save a snapshot with a message.
git push	Upload your commits to the remote.
git pull	Download updates from the remote.
git branch	Create or list branches.
git checkout	Move between branches or commits.
git restore	Undo changes before committing.
git log	See what’s been committed.

Demo: A Real Git Workflow

Bonus: git worktree

Enables you to check out multiple branches at the same time. Useful when hotfixing.

Add worktree

git worktree add "$TARGET_DIR" "$SELECTED_BRANCH"

checks out $SELECTED_BRANCH into $TARGET_DIR and creates a worktree registration inside the .git/worktrees/ directory of your current repo

avoid using git worktree add from short living branches

Remove worktree

git worktree remove "$TARGET_DIR"

• unregisters the worktree (removes its metadata from .git/worktrees/)
• safely deletes the directory for you (unless you use --keep).
