Struggling to understand Git? Let’s simplify it step-by-step — from setup to pushing your first code.

---

🚀 What Is Git?

Git is a version control system. Think of it as a time machine for your code — it tracks every change, helps you collaborate, and lets you roll back if something breaks.

---

🔧 Prerequisites

• Git installed on your computer → Download Git

• A GitHub account → Create one here

• A folder/project on your machine

---

✅ Step-by-Step Guide

1️⃣ Set Up Git (Only Once)

git config --global user.name "Your Name"
git config --global user.email "you@example.com"

2️⃣ Initialize Your Local Git Repo

cd your-project-folder
git init

This starts Git version tracking in your folder.

---

3️⃣ Stage and Commit Your Code

git add .
git commit -m "Initial commit"

This saves a snapshot of your files.

---

4️⃣ Create a GitHub Repository

1. Go to GitHub

2. Click New Repository

3. Name it (e.g., my-first-repo)

4. Keep it empty (no README or .gitignore)

5. Click Create Repository

---

5️⃣ Link Your Local Repo to GitHub

Copy the repo URL GitHub gives you and run:

git remote add origin https://github.com/yourusername/my-first-repo.git

---

6️⃣ Push Your Code to GitHub

For older Git versions:

git push -u origin master

For newer Git:

git push -u origin main

🎉 That’s it! Your code is now live on GitHub.

---

🛠️ Common Git Errors and Fixes

🔸 Error: remote origin already exists

git remote remove origin
git remote add origin <url>

🔸 Error: Updates were rejected...

git pull origin main --allow-unrelated-histories
git push -u origin main
