What is Git?

Version Control System (VCS)

• Track changes in your code over time
• Collaborate with teammates without conflicts
• Revert to previous versions when needed
• Branch to experiment safely

💡 Git is the most popular VCS used by millions of developers worldwide

Git Configuration (First Time Setup)

Before using Git, configure your identity:

# Set your name
git config --global user.name "Your Name"

# Set your email
git config --global user.email "your.email@example.com"

# Check your configuration
git config --list

# Example:
git config --global user.name "Mahfuz Ibne Syful"
git config --global user.email "mahfuzibnesyful24@gmail.com"

💡 Use the same email as your GitHub account!

Git Core Commands

# Initialize a new repository
git init

# Check status of files
git status

# Stage files for commit
git add <file>
git add .

# Commit changes
git commit -m "Your message"

# View commit history
git log --oneline --graph --decorate

What is GitHub?

Connecting to GitHub

# Clone existing repo
git clone <url>

# Add remote to local repo
git remote add origin <url>

# Push to GitHub
git push -u origin main

# Pull latest changes
git pull

Markdown Basics

# Heading 1
## Heading 2
### Heading 3

*italic text*

- Bullet point
1. Numbered list

[Link text](url)

```code block```
`inline code`

README.md Best Practices

• Project title and description
• Installation instructions
• Usage examples
• Contributing guidelines
• License information
• Add badges, screenshots, demos!

🛠️ Hands-on Exercise

Let's Do This Together!

1. Create a new folder for your project
2. Initialize Git: git init
3. Create README.md with Markdown
4. Stage and commit: git add . && git commit -m "Initial commit"
5. Create GitHub repo (on github.com)
6. Add remote and push: git remote add origin <url>
7. Verify your repo on GitHub! 🎉

📚 Homework

• Make one small change to your README.md
• Commit and push the change
• Be ready to open a Pull Request on Day 2!
