✅ Git Basics You Should Know 🛠️📁

Git is a version control system used to track changes in your code, collaborate with others, and manage project history efficiently.

1️⃣ What is Git?
Git lets you save snapshots of your code, go back to previous versions, and collaborate with teams without overwriting each other’s work. 📸

2️⃣ Install & Setup Git
git --version # Check if Git is installed
git config --global user.name "Your Name"
git config --global user.email "you@example.com"

3️⃣ Initialize a Repository
git init # Start a new local Git repo 🚀

4️⃣ Basic Workflow
git add . # Stage all changes ➕
git commit -m "Message" # Save a snapshot 💾
git push # Push to remote (like GitHub) ☁️

5️⃣ Check Status & History
git status # See current changes 🚦
git log # View commit history 📜

6️⃣ Clone a Repo
git clone https://github.com/username/repo.git 👯

7️⃣ Branching
git branch feature-x # Create a branch 🌳
git checkout feature-x # Switch to it ↔️
git merge feature-x # Merge with main branch 🤝

8️⃣ Undo Mistakes ↩️
git checkout -- file.txt # Discard changes
git reset HEAD~1 # Undo last commit (local)
git revert <commit_id> # Revert commit (safe)

9️⃣ Working with GitHub
– Create repo on GitHub ✨
– Link local repo:
git remote add origin <repo_url>
git push -u origin main

🔟 Git Best Practices
– Commit often with clear messages ✅
– Use branches for features/bugs 💡
– Pull before push 🔄
– Never commit sensitive data 🔒

💡 Tip: Use GitHub Desktop or VS Code Git UI if CLI feels hard at first.
