Module 01: Git Basics

Learning Objectives

• Understand what a git repository is
• Learn the basic git workflow: modify → stage → commit
• Use git status to check repository state
• Use git add to stage changes
• Use git commit to save changes

Challenge

In this challenge, you'll learn the fundamental git workflow.

Setup

Run the setup script to prepare the challenge:

.\setup.ps1

This will create a directory called challenge with some files that need to be committed.

Your Task

1. Navigate into the challenge directory: cd challenge
2. Initialize a new git repository: git init (this is your first step!)
3. Check the status of your repository: git status
4. Stage the file welcome.txt: git add welcome.txt
5. Create a commit with the message "Add welcome file": git commit -m "Add welcome file"
6. Stage the file instructions.txt: git add instructions.txt
7. Create a commit with the message "Add instructions": git commit -m "Add instructions"

Note: The challenge directory is NOT a git repository until you run git init. This is intentional - you're learning to start from scratch!

Key Concepts

• Repository: A directory tracked by git, containing your project files and their history
• Working Directory: The files you see and edit
• Staging Area (Index): A preparation area for your next commit
• Commit: A snapshot of your staged changes

Useful Commands

git init                    # Initialize a new git repository
git status                  # Show the working tree status
git add <file>              # Stage a file for commit
git commit -m "<message>"   # Create a commit with a message

Verification

Once you think you've completed the challenge, run:

.\verify.ps1

This will check if you've successfully completed all the steps.
