+## Overview
+
+`winctl.sh` is a management script for running Windows virtual machines inside Docker containers. It provides:
+
+- **22 Windows versions** from Windows 2000 to Windows 11
+- **Simple commands** to start, stop, and manage containers
+- **Interactive menus** when you don't specify a version
+- **Status caching** for fast performance
+- **Resource profiles** optimized for modern and legacy systems
+

+
+## Prerequisites
+
+### Required
+
+1. **Docker** - Container runtime
+2. **Docker Compose** - Container orchestration (plugin or standalone)
+3. **KVM** - Hardware virtualization for near-native performance
+
+### Check Prerequisites
+
+Run the built-in check:
+
+```bash
+./winctl.sh check
+```
+
+Example output:
+```
+Prerequisites Check
+────────────────────────────────────────────────────────────
+[OK] Docker is available
+[OK] Docker Compose plugin is available
+[OK] KVM is available
+[OK] TUN device is available
+[OK] Memory OK: 16GB available (8GB needed)
+[OK] Disk space OK: 500GB available (128GB needed)
+
+[OK] All critical prerequisites passed!
+```
+
+### Fix Common Issues
+
+**KVM not accessible:**
+```bash
+sudo usermod -aG kvm $USER
+newgrp kvm  # or log out and back in
+```
+
+**Docker not running:**
+```bash
+sudo systemctl start docker
+```
+
+---
+
+## Quick Start
+
+### 1. Start a Windows VM
+
+```bash
+# Start Windows 11
+./winctl.sh start win11
+
+# Or use interactive menu
+./winctl.sh start
+```
+
+### 2. Access the VM
+
+After starting, you'll see connection details:
+
+```
+Connection Details:
+  → Web Viewer: http://localhost:8011
+  → RDP:        localhost:3311
+```
+
+- **Web Viewer**: Open in browser for quick access
+- **RDP**: Use any RDP client for better performance
+
+### 3. Check Status
+
+```bash
+./winctl.sh status
+```
+
+### 4. Stop the VM
+
+```bash
+./winctl.sh stop win11
+```
+
+---
+
+## Commands Reference
+
+### start
+
+Start one or more containers.
+
+```bash
+# Start single version
+./winctl.sh start win11
+
+# Start multiple versions
+./winctl.sh start win11 win10 winxp
+
+# Interactive menu (no version specified)
+./winctl.sh start
+```
+
+**What it does:**
+1. Checks prerequisites (Docker, KVM)
+2. Creates data directory if missing
+3. Checks available resources
+4. Starts the container
+5. Shows connection details
+
+---
+
+### stop
+
+Stop containers with a 2-minute grace period for clean shutdown.

+```bash
+# Stop single version
+./winctl.sh stop win11
+
+# Stop multiple versions
+./winctl.sh stop win11 win10
+
+# Interactive menu
+./winctl.sh stop
+```
+
+**Note:** You'll be asked to confirm before stopping.
+
+---
+
+### restart
+
+Restart containers.
+
+```bash
+./winctl.sh restart win11

+
+---
+
+### status
+
+Show status of containers.
+
+```bash
+# All containers

+
+## Common Scenarios
+
+### Scenario 1: Set Up a Development Environment
+
+```bash
+# Start Windows 10 for development
+./winctl.sh start win10
+
+# Access via web browser
+# Open http://localhost:8010
+
+# Or connect via RDP for better performance
+# Use RDP client to connect to localhost:3310
+```
+
+### Scenario 2: Test Software on Multiple Windows Versions
+
+```bash
+# Start multiple versions
+./winctl.sh start win11 win10 win7
+
+# Check they're all running
+./winctl.sh status
+
+# Access each via their ports:
+# - Win11: http://localhost:8011
+# - Win10: http://localhost:8010
+# - Win7:  http://localhost:8007
+
+# Stop all when done
+./winctl.sh stop win11 win10 win7
+```
+
+### Scenario 3: Run Legacy Software on Windows XP
+
+```bash
+# Start Windows XP
+./winctl.sh start winxp
+
+# Access via http://localhost:8005
+# Login: docker / admin
+
+# Transfer files via the Shared folder on desktop
+```
+
+### Scenario 4: Monitor Resource Usage
+
+```bash
+# See real-time stats for all running VMs
+./winctl.sh stats
+
+# Or use the dashboard
+./winctl.sh monitor
+```
+
+### Scenario 5: Increase Resources for a VM
+
+1. Stop the container:
+   ```bash
+   ./winctl.sh stop win11
+   ```
+
+2. Edit `.env.modern`:
+   ```bash
+   RAM_SIZE=16G
+   CPU_CORES=8
+   ```
+
+3. Start again:
+   ```bash
+   ./winctl.sh start win11
+   ```
+
+### Scenario 6: Fresh Start (Reset VM)
+
+```bash
+# This destroys the container but keeps data
+./winctl.sh rebuild win11
+
+# For a complete reset, also delete the data:
+rm -rf data/win11/*
+./winctl.sh start win11
+```
+
+---
+
+## Troubleshooting
+
+### Container Won't Start
+
+**Check prerequisites:**
+```bash
+./winctl.sh check
+```
+
+**Check logs:**
+```bash
+./winctl.sh logs win11
+```
+
+**Common issues:**
+- KVM not accessible → Add user to kvm group
+- Port already in use → Stop other containers or services
+- Not enough disk space → Free up space or reduce DISK_SIZE
+
+### Slow Performance
+
+- Ensure KVM is working (hardware virtualization)
+- Increase RAM_SIZE and CPU_CORES in env file
+- Use RDP instead of web viewer for better performance
+
+### Can't Connect via RDP
+
+1. Wait for Windows to fully boot (check web viewer first)
+2. RDP might be disabled in Windows → Enable via web viewer
+3. Check firewall settings in Windows
+
+### Web Viewer Not Loading
+
+```bash
+# Check if container is running
+./winctl.sh status win11
+
+# Check container logs
+./winctl.sh logs win11
+
+# Restart the container
+./winctl.sh restart win11
+```
+
+### Cache Issues
+
+Force refresh the status cache:
+```bash
+./winctl.sh refresh
+```
+
+---
+
+## Tips & Tricks
+
+### 1. Use Aliases
+
+Add to your `~/.bashrc`:
+```bash
+alias wctl='./winctl.sh'
+alias wstart='./winctl.sh start'
+alias wstop='./winctl.sh stop'
+alias wstatus='./winctl.sh status'
+```
+
+### 2. Quick Access Bookmarks
+
+Bookmark your commonly used VMs:
+- Windows 11: http://localhost:8011
+- Windows 10: http://localhost:8010
+
+### 3. File Sharing
+
+Each VM has a "Shared" folder on the desktop that maps to the host. Use this to transfer files.
+
+### 4. Snapshots via Data Backup
+
+The VM disk is stored in `data/<version>/`. Back it up to create a snapshot:
+```bash
+./winctl.sh stop win11
+cp -r data/win11 data/win11-backup
+./winctl.sh start win11
+```
+
+### 5. Running Multiple VMs
+
+Check your available resources before starting multiple VMs:
+```bash
+# Each modern VM needs 8GB RAM
+# Each legacy VM needs 2GB RAM
+
+# Example: Running win11 + win10 + winxp = 8+8+2 = 18GB RAM needed
+```
+
+### 6. Headless Operation
+
+For servers, you can start VMs and access only via RDP:
+```bash
+./winctl.sh start win2022
+# Connect via RDP to localhost:3322
+```
+
+---
