+# Linux System Tuning Suite
+
+🚀 **Intelligent system optimization toolkit for Linux desktop systems**
+
+This repository provides automated system tuning based on hardware detection, usage patterns, and best practices for tmpfs, overlay filesystems, and kernel parameter optimization.
+
+## 🎯 Features
+
+- **Hardware Detection**: Automatically detects RAM, CPU, storage configuration
+- **Usage Analysis**: Identifies frequently accessed files and directories
+- **Intelligent Tuning**: Applies optimizations based on system characteristics
+- **Modular Design**: Easy to customize and extend
+- **Safe Deployment**: Backup and rollback capabilities
+- **Multi-Distribution**: Works across different Linux distributions
+
+## 🏗️ Components
+
+### Core Scripts
+- `tune-system.sh` - Main tuning orchestrator
+- `system-analyzer.sh` - Hardware and usage analysis
+- `optimizer.sh` - Apply specific optimizations
+- `monitor.sh` - System monitoring and health checks
+
+### Modules
+- `modules/hardware-detection.sh` - RAM, CPU, storage detection
+- `modules/usage-analysis.sh` - File access pattern analysis
+- `modules/tmpfs-optimizer.sh` - tmpfs configuration
+- `modules/overlay-optimizer.sh` - overlay filesystem setup
+- `modules/kernel-tuning.sh` - kernel parameter optimization
+- `modules/zram-optimizer.sh` - zram/zswap configuration
+
+### Profiles
+- `profiles/` - Pre-configured optimization profiles
+- `configs/` - Configuration templates
+
+## 🚀 Quick Start
+
+```bash
+# Clone the repository
+git clone git@gitea.egonetix.de:root/linux_system_tuning.git
+cd linux_system_tuning
+
+# Run system analysis
+sudo ./system-analyzer.sh
+
+# Apply optimizations
+sudo ./tune-system.sh --auto
+
+# Monitor results
+./monitor.sh
+```
+
+## 📊 Supported Optimizations
+
+- **Memory Management**: zram, tmpfs, overlay filesystems
+- **Kernel Tuning**: vm parameters, scheduler settings
+- **Cache Optimization**: Browser, IDE, package manager caches
+- **I/O Optimization**: Storage and network tuning
+- **Desktop Responsiveness**: Priority and scheduling tweaks
+
+## 🔧 Configuration
+
+The system can be configured through:
+- Interactive setup wizard
+- Configuration files
+- Command-line parameters
+- Environment variables
+
+## 📈 Benchmarking
+
+Built-in benchmarking tools to measure:
+- Boot time improvements
+- Application startup times
+- Memory utilization efficiency
+- I/O performance gains
+
+## 🛡️ Safety
+
+- Automatic backups before changes
+- Rollback capabilities
+- Safe mode for testing
+- Validation checks
