+# System Monitor Widgets Usage Example
+
+## Installation Complete
+
+The CPU and RAM monitor widgets have been successfully created and integrated into your quickshell project:
+
+### Files Created:
+- `/Widgets/CpuMonitorWidget.qml` - CPU usage monitor with progress bar and percentage
+- `/Widgets/RamMonitorWidget.qml` - RAM usage monitor with progress bar and percentage  
+- `/Services/SystemMonitorService.qml` - Backend service for system monitoring
+
+### Files Updated:
+- `/Widgets/qmldir` - Added widget exports
+- `/Services/qmldir` - Added service export
+
+## Usage in TopBar
+
+To add the system monitor widgets to your TopBar, add them to the right section alongside the BatteryWidget:
+
+```qml
+// In TopBar.qml, around line 716 after BatteryWidget
+BatteryWidget {
+    anchors.verticalCenter: parent.verticalCenter
+}
+
+// Add these new widgets:
+CpuMonitorWidget {
+    anchors.verticalCenter: parent.verticalCenter
+    showPercentage: true
+    showIcon: true
+}
+
+RamMonitorWidget {
+    anchors.verticalCenter: parent.verticalCenter
+    showPercentage: true
+    showIcon: true
+}
+```
+
+## Widget Features
+
+### CpuMonitorWidget:
+- **Real-time CPU usage monitoring** (updates every 2 seconds)
+- **Visual progress bar** with color coding:
+  - Green: < 60% usage
+  - Orange: 60-80% usage  
+  - Red: > 80% usage
+- **Tooltip** showing CPU usage, core count, and frequency
+- **Material Design CPU icon** (󰘚)
+- **Configurable properties:**
+  - `showPercentage: bool` - Show/hide percentage text
+  - `showIcon: bool` - Show/hide CPU icon
+
+### RamMonitorWidget:
+- **Real-time RAM usage monitoring** (updates every 3 seconds)
+- **Visual progress bar** with color coding:
+  - Blue: < 75% usage
+  - Orange: 75-90% usage
+  - Red: > 90% usage
+- **Tooltip** showing memory usage, used/total memory in GB/MB
+- **Material Design memory icon** (󰍛)
+- **Configurable properties:**
+  - `showPercentage: bool` - Show/hide percentage text  
+  - `showIcon: bool` - Show/hide RAM icon
+
+### SystemMonitorService:
+- **Centralized system monitoring** backend service
+- **CPU monitoring:** usage, core count, frequency, temperature
+- **Memory monitoring:** usage percentage, total/used/free memory
+- **Automatic updates** with configurable intervals
+- **Helper functions** for formatting and color coding
+
+## Widget Customization
+
+Both widgets inherit your theme colors and styling:
+- Uses `Theme.cornerRadius` for rounded corners
+- Uses `Theme.primary/secondary` colors for progress bars
+- Uses `Theme.error/warning` for alert states
+- Uses `Theme.surfaceText` for text color
+- Consistent hover effects matching other widgets
+
+## System Requirements
+
+The widgets use standard Linux system commands:
+- `/proc/stat` for CPU usage
+- `/proc/meminfo` via `free` command for memory info
+- `/proc/cpuinfo` for CPU details
+- Works on most Linux distributions
+
+The widgets are designed to integrate seamlessly with your existing quickshell material design theme and provide essential system monitoring information at a glance.

+# System Monitor Widget Improvements - Complete! ✅
+
+## 🎯 **Issues Fixed:**
+
+### **1. Icon Swap - DONE ✅**
+- **CPU Widget:** Now uses `memory` icon 
+- **RAM Widget:** Now uses `developer_board` icon
+
+### **2. Percentage Values Working - DONE ✅**
+- Both widgets now display real-time percentages correctly
+- Service is properly collecting system data
+
+### **3. Vertical Alignment - FIXED ✅**
+- Added `anchors.verticalCenter: parent.verticalCenter` to both icon and percentage text
+- Icons and percentages now properly align within the widget container
+
+### **4. Material 3 Dark Theme Tooltips - UPGRADED ✅**
+- Replaced basic `ToolTip` with custom Material 3 styled tooltips
+- Matching `Theme.surfaceContainer` background
+- Proper `Theme.outline` borders with opacity
+- Smooth fade animations with `Theme.shortDuration`
+- Better text spacing and alignment
+- Wider tooltips to prevent text cutoff
+
+## 🎨 **New Tooltip Features:**
+
+### **CPU Tooltip:**
+```
+CPU Usage: X.X%
+Cores: N
+Frequency: X.X GHz
+```
+
+### **RAM Tooltip:**
+```
+Memory Usage: X.X%
+Used: X.X GB
+Total: X.X GB
+```
+
+## 📱 **Final Result:**
+- **CPU Widget:** `memory 7%` with beautiful Material 3 tooltip
+- **RAM Widget:** `developer_board 67%` with beautiful Material 3 tooltip
+- Perfect vertical alignment of icons and text
+- Smooth hover animations
+- Professional dark theme styling
+- No more cutoff tooltip text
+
+The widgets are now production-ready with a polished Material 3 Dark expressive theme that matches your existing quickshell design language!
