+# Installation Guide for Windows 11
+
+This guide will help you install everything needed for the Git Workshop on Windows 11.
+
+## Prerequisites
+
+You'll need administrator access to install software on your Windows 11 machine.
+
+## What You'll Install
+
+1. **PowerShell 7** - Modern cross-platform PowerShell (replaces the older Windows PowerShell 5.1)
+2. **Git** - Version control system (2.23 or later)
+3. **Visual Studio Code** - Modern code editor with excellent Git integration
+
+## Installation Steps
+
+### 1. Install PowerShell 7
+
+PowerShell 7 is the modern, cross-platform version of PowerShell. Windows 11 comes with PowerShell 5.1, but we recommend PowerShell 7 for the best experience.
+
+**Option A: Using winget (Recommended)**
+
+Open **Windows Terminal** or **Command Prompt** and run:
+
+```powershell
+winget install --id Microsoft.PowerShell --source winget
+```
+
+**Option B: Manual Download**
+
+1. Visit https://github.com/PowerShell/PowerShell/releases/latest
+2. Download the file ending in `-win-x64.msi` (e.g., `PowerShell-7.4.1-win-x64.msi`)
+3. Run the installer
+4. Accept all defaults
+
+**Verify Installation:**
+
+Open a new terminal and run:
+
+```powershell
+pwsh --version
+```
+
+You should see version 7.x.x or higher.
+
+**Important:** After installing PowerShell 7, use it instead of the older "Windows PowerShell 5.1". Look for "PowerShell 7" in your Start menu or Windows Terminal.
+
+### 2. Install Git
+
+Git is the version control system you'll learn in this workshop. You need version 2.23 or later.
+
+**Option A: Using winget (Recommended)**
+
+```powershell
+winget install --id Git.Git -e --source winget
+```
+
+**Option B: Manual Download**
+
+1. Visit https://git-scm.com/downloads
+2. Click "Windows"
+3. Download the 64-bit installer
+4. Run the installer with these recommended settings:
+   - **Default editor**: Choose "Visual Studio Code" (we'll install it next)
+   - **PATH environment**: Select "Git from the command line and also from 3rd-party software"
+   - **Line ending conversions**: Choose "Checkout Windows-style, commit Unix-style line endings"
+   - **Terminal emulator**: Choose "Use Windows' default console window"
+   - All other settings: Accept defaults
+
+**Verify Installation:**
+
+Open a **new** PowerShell window and run:
+
+```powershell
+git --version
+```
+
+You should see version 2.23 or higher (e.g., `git version 2.43.0`).
+
+### 3. Install Visual Studio Code
+
+VS Code is a free, powerful code editor with excellent Git integration.
+
+**Option A: Using winget (Recommended)**
+
+```powershell
+winget install --id Microsoft.VisualStudioCode --source winget
+```
+
+**Option B: Manual Download**
+
+1. Visit https://code.visualstudio.com/
+2. Click "Download for Windows"
+3. Run the installer
+4. During installation, check these options:
+   - ✅ Add "Open with Code" action to Windows Explorer file context menu
+   - ✅ Add "Open with Code" action to Windows Explorer directory context menu
+   - ✅ Register Code as an editor for supported file types
+   - ✅ Add to PATH
+
+**Verify Installation:**
+
+```powershell
+code --version
+```
+
+You should see version information.
+
+**Recommended VS Code Extensions:**
+
+Open VS Code and install these extensions for the best Git experience:
+
+1. **GitLens** - Supercharge Git capabilities
+   - Press `Ctrl+Shift+X` to open Extensions
+   - Search for "GitLens"
+   - Click Install
+
+2. **Git Graph** - View Git history visually
+   - Search for "Git Graph"
+   - Click Install
+
+3. **PowerShell** - Better PowerShell support
+   - Search for "PowerShell"
+   - Install the one from Microsoft
+
+## Configure Git
+
+Before making your first commit, tell Git who you are:
+
+```powershell
+git config --global user.name "Your Name"
+git config --global user.email "your.email@example.com"
+```
+
+**Verify your configuration:**
+
+```powershell
+git config --global user.name
+git config --global user.email
+```
+
+You should see your name and email printed.
+
+**Optional: Set VS Code as Git's Default Editor**
+
+If you installed Git before VS Code, configure Git to use VS Code:
+
+```powershell
+git config --global core.editor "code --wait"
+```
+
+## PowerShell Execution Policy
+
+When running PowerShell scripts (`.ps1` files) in this workshop, you might encounter an error about execution policies.
+
+**If you see an error like "script cannot be loaded because running scripts is disabled":**
+
+Open **PowerShell 7 as Administrator** and run:
+
+```powershell
+Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser
+```
+
+This allows you to run local scripts while maintaining security for downloaded scripts.
+
+## Running Scripts in the Workshop
+
+After installation, you can run workshop scripts using:
+
+```powershell
+.\setup.ps1
+.\verify.ps1
+.\reset.ps1
+```
+
+**Example workflow:**
+
+```powershell
+# Navigate to a module
+cd 01-essentials\01-basics
+
+# Run the setup script
+.\setup.ps1
+
+# Complete the challenge using Git commands
+# ...
+
+# Verify your solution
+.\verify.ps1
+```
+
+## Optional: Python (for Module 08 only)
+
+Module 08 (Multiplayer Git) uses Python for "The Great Print Project". You only need this for that specific module.
+
+**Install Python 3.12:**
+
+```powershell
+winget install --id Python.Python.3.12 --source winget
+```
+
+**Verify installation:**
+
+```powershell
+python --version
+```
+
+You should see Python 3.12.x or higher.
+
+## Optional: Windows Terminal (Highly Recommended)
+
+Windows Terminal provides a modern terminal experience with tabs, better colors, and PowerShell 7 integration.
+
+**Install:**
+
+```powershell
+winget install --id Microsoft.WindowsTerminal --source winget
+```
+
+Or install from the **Microsoft Store** (search for "Windows Terminal").
+
+**After installation:**
+- Press `Win+X` and select "Windows Terminal"
+- Or search "Terminal" in the Start menu
+- PowerShell 7 should be the default profile
+
+## Verify Complete Installation
+
+Run these commands to verify everything is installed correctly:
+
+```powershell
+# PowerShell version (should be 7.x.x)
+pwsh --version
+
+# Git version (should be 2.23 or higher)
+git --version
+
+# VS Code version
+code --version
+
+# Git configuration
+git config --global user.name
+git config --global user.email
+
+# Optional: Python (for Module 08)
+python --version
+```
+
+## Troubleshooting
+
+### Git command not found
+
+If `git --version` doesn't work after installation:
+1. Close and reopen your terminal (Git needs a new terminal to update PATH)
+2. Restart your computer if the problem persists
+
+### VS Code command not found
+
+If `code --version` doesn't work:
+1. Ensure you checked "Add to PATH" during installation
+2. Close and reopen your terminal
+3. If still not working, reinstall VS Code with the PATH option enabled
+
+### PowerShell execution policy errors
+
+If you can't run `.ps1` scripts:
+1. Open PowerShell 7 **as Administrator**
+2. Run: `Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser`
+3. Close admin PowerShell and try again in a regular PowerShell window
+
+### winget command not found
+
+If `winget` doesn't work:
+1. Update Windows 11 to the latest version (Settings → Windows Update)
+2. Install "App Installer" from the Microsoft Store
+3. Restart your computer
+
+## You're Ready!
+
+Once all verification commands work, you're ready to start the workshop!
+
+```powershell
+# Clone or download the git-workshop repository
+# Navigate to it
+cd path\to\git-workshop
+
+# Start with Module 01
+cd 01-essentials\01-basics
+
+# Read the instructions
+code README.md
+
+# Run setup and begin!
+.\setup.ps1
