⚙️ First-Time Git Setup

---

🎯 Goal

Configure Git so your commits have identity.

---

🧠 Why This Matters

Every commit in Git stores:

• author name
• email
• timestamp

Without setup → commits are incomplete or incorrect.

---

✅ Basic Setup Commands

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

---

🧪 Verify Setup

git config --list

---

📸 Visual (Config Flow)

---

🏗 Internal Architecture

Git stores config in 3 levels:

1. System Level

/etc/gitconfig

2. Global Level (most common)

~/.gitconfig

3. Local Level (per repo)

.git/config

---

🔬 Example .gitconfig

[user]
    name = Your Name
    email = your@email.com

---

🧠 Priority Order

Local > Global > System

👉 Local overrides global

---

⚠️ Common Mistakes

• forgetting to set email
• wrong identity in commits
• mixing work & personal emails

---

🧠 Memory Trick

Config = identity for commits
