+# Container Monitor TUI
+
+A beautiful terminal-based container monitoring tool that combines syscall tracking, file I/O monitoring, and network traffic analysis using eBPF.
+
+## Features
+
+- 🎯 **Interactive Cgroup Selection** - Navigate and select cgroups with arrow keys
+- 📊 **Real-time Monitoring** - Live graphs and statistics
+- 🔥 **Syscall Tracking** - Total syscall count per cgroup
+- 💾 **File I/O Monitoring** - Read/write operations and bytes with graphs
+- 🌐 **Network Traffic** - RX/TX packets and bytes with live graphs
+- ⚡ **Efficient Caching** - Reduced /proc lookups for better performance
+- 🎨 **Beautiful TUI** - Clean, colorful terminal interface
+
+## Requirements
+
+- Python 3.7+
+- pythonbpf
+- Root privileges (for eBPF)
+
+## Installation
+
+```bash
+# Ensure you have pythonbpf installed
+pip install pythonbpf
+
+# Run the monitor
+sudo $(which python) container_monitor.py
+```
+
+## Usage
+
+1. **Selection Screen**: Use ↑↓ arrow keys to navigate through cgroups, press ENTER to select
+2. **Monitoring Screen**: View real-time graphs and statistics, press ESC or 'b' to go back
+3. **Exit**: Press 'q' at any time to quit
+
+## Architecture
+
+- `container_monitor.py` - Main BPF program combining all three tracers
+- `data_collector.py` - Data collection, caching, and history management
+- `tui. py` - Terminal user interface with selection and monitoring screens
+
+## BPF Programs
+
+- **vfs_read/vfs_write** - Track file I/O operations
+- **__netif_receive_skb/__dev_queue_xmit** - Track network traffic
+- **raw_syscalls/sys_enter** - Count all syscalls
+
+All programs filter by cgroup ID for per-container monitoring.
