Complete Linux system optimization suite with tmpfs, zram, and German locale support

- Fixed missing setup_tmpfs() function that was causing silent failures
- Added comprehensive system scanning for browsers, IDEs, gaming caches
- Implemented detailed optimization information display for transparency
- Added German locale compatibility for 'free' command (Speicher: vs Mem:)
- Fixed division by zero errors in RAM calculations
- Created tmpfs-info.sh helper script for detailed status reporting
- Enhanced scanning to work on already-optimized systems
- Added comprehensive optimization breakdowns with purpose explanations

+# 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.
+
+## ✨ **NEW: One-Button Optimizer**
+
+🎯 **Quick Start:** `sudo ./one-button-optimizer.sh`
+
+The **one-button optimizer** is an intelligent, interactive system optimizer that:
+
+- 🔍 **Analyzes current optimizations** and detects suboptimal configurations
+- 🤔 **Prompts for user choice** on each optimization 
+- 🎯 **Applies only selected optimizations** - no forced changes
+- ✅ **Recognizes existing optimal configurations** and leaves them alone
+- ⚙️ **Handles mixed scenarios** where some optimizations exist but aren't ideal
+
+### Quick Tools
+
+- `./one-button-optimizer.sh` - **Main interactive optimizer** (recommended)
+- `./quick-status-check.sh` - **Quick system status** overview (no changes)
+- `./tmpfs-info.sh` - **Detailed tmpfs information** and configuration guide
+- `./launcher.sh` - **Auto-sudo launcher** for the optimizer
+
+## 🎯 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
+- **Interactive Mode**: User control over what gets optimized
+- **Suboptimal Detection**: Finds and offers to fix existing but suboptimal configs
+- **Modular Design**: Easy to customize and extend
+- **Safe Deployment**: Backup and rollback capabilities
+- **Multi-Distribution**: Works across different Linux distributions
+
+## 🏗️ Components
+
+### Core Scripts
+- `one-button-optimizer.sh` - **🆕 Interactive one-button optimizer** 
+- `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/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
