+# HeroRun - AI Agent Optimized Container Management
+
+**Production-ready scripts for fast remote command execution**
+
+## 🎯 Purpose
+
+Optimized for AI agents that need rapid, reliable command execution with minimal latency and clean output.
+
+## 🏗️ Base Image Types
+
+HeroRun supports different base images through the `BaseImage` enum:
+
+```v
+pub enum BaseImage {
+    alpine        // Standard Alpine Linux minirootfs (~5MB)
+    alpine_python // Alpine Linux with Python 3 pre-installed
+}
+```
+
+### Usage Examples
+
+**Standard Alpine Container:**
+
+```v
+base_image: .alpine  // Default - minimal Alpine Linux
+```
+
+**Alpine with Python:**
+
+```v
+base_image: .alpine_python  // Python 3 + pip pre-installed
+```
+
+## 📋 Three Scripts
+
+### 1. `setup.vsh` - Environment Preparation
+
+Creates container infrastructure on remote node.
+
+```bash
+./setup.vsh
+```
+
+**Output:** `Setup complete`
+
+### 2. `execute.vsh` - Fast Command Execution  
+
+Executes commands on remote node with clean output only.
+
+```bash
+./execute.vsh "command" [context_id]
+```
+
+**Examples:**
+
+```bash
+./execute.vsh "ls /containers"
+./execute.vsh "whoami"
+./execute.vsh "echo 'Hello World'"
+```
+
+**Output:** Command result only (no verbose logging)
+
+### 3. `cleanup.vsh` - Complete Teardown
+
+Removes container and cleans up all resources.
+
+```bash
+./cleanup.vsh  
+```
+
+**Output:** `Cleanup complete`
+
+## ⚡ Performance Features
+
+- **Clean Output**: Execute returns only command results
+- **No Verbose Logging**: Silent operation for production use
+- **Fast Execution**: Direct SSH without tmux overhead
+- **AI Agent Ready**: Perfect for automated command execution
+
+## 🚀 Usage Pattern
+
+```bash
+# Setup once
+./setup.vsh
+
+# Execute many commands (fast)
+./execute.vsh "ls -la"
+./execute.vsh "ps aux" 
+./execute.vsh "df -h"
+
+# Cleanup when done
+./cleanup.vsh
+```
+
+## 🎯 AI Agent Integration
+
+Perfect for AI agents that need:
+
+- Rapid command execution
+- Clean, parseable output  
+- Minimal setup overhead
+- Production-ready reliability
+
+Each execute call returns only the command output, making it ideal for AI agents to parse and process results.

+# HeroRun - Remote Container Management
+
+A V library for managing remote containers using runc and tmux, with support for multiple cloud providers.
+
+## Features
+
+- **Multi-provider support**: Currently supports Hetzner, with ThreeFold coming soon
+- **Automatic setup**: Installs required packages (runc, tmux, curl, xz-utils) automatically
+- **Container isolation**: Uses runc for lightweight container management
+- **tmux integration**: Each container gets its own tmux session for multiple concurrent shells
+- **Clean API**: Simple interface that hides infrastructure complexity
+
+## Project Structure
+
+```txt
+lib/virt/herorun/
+├── interfaces.v          # Shared interfaces and parameter structs
+├── nodes.v               # Node management and SSH connectivity
+├── container.v           # Container struct and lifecycle operations
+├── executor.v            # Optimized command execution engine
+├── factory.v             # Provider abstraction and backend creation
+├── hetzner_backend.v     # Hetzner cloud implementation
+└── README.md            # This file
+```
+
+## Usage
+
+### Basic Example
+
+```v
+import freeflowuniverse.herolib.virt.herorun
+
+// Create user with SSH key
+mut user := herorun.new_user(keyname: 'id_ed25519')!
+
+// Create Hetzner backend
+mut backend := herorun.new_hetzner_backend(
+    node_ip: '65.21.132.119'
+    user:    'root'
+)!
+
+// Connect to node (installs required packages automatically)
+backend.connect(keyname: user.keyname)!
+
+// Send a test command to the node
+backend.send_command(cmd: 'ls')!
+
+// Get or create container (uses tmux behind the scenes)
+mut container := backend.get_or_create_container(name: 'test_container')!
+
+// Attach to container tmux session
+container.attach()!
+
+// Send command to container
+container.send_command(cmd: 'ls')!
+
+// Get container logs
+logs := container.get_logs()!
+println('Container logs:')
+println(logs)
+
+```
+
+### Running the Example
+
+```bash
+# Make the example executable
+chmod +x examples/virt/herorun/herorun.vsh
+
+# Run it
+./examples/virt/herorun/herorun.vsh
+```
+
+## Architecture
+
+### Interfaces
+
+- **NodeBackend**: Defines operations for connecting to and managing remote nodes
+- **ContainerBackend**: Defines operations for container lifecycle management
+
+### Providers
+
+- **HetznerBackend**: Implementation for Hetzner cloud servers
+- **ThreeFoldBackend**: (Coming soon) Implementation for ThreeFold nodes
+
+### Key Components
+
+1. **SSH Integration**: Uses herolib's sshagent module for secure connections
+2. **tmux Management**: Uses herolib's tmux module for session management
+3. **Container Runtime**: Uses runc for lightweight container execution
+4. **Hetzner Integration**: Uses herolib's hetznermanager module
+
+## Dependencies
+
+- `freeflowuniverse.herolib.osal.sshagent`
+- `freeflowuniverse.herolib.osal.tmux`
+- `freeflowuniverse.herolib.installers.web.hetznermanager`
+- `freeflowuniverse.herolib.ui.console`
+
+## Future Enhancements
+
+- ThreeFold backend implementation
+- Support for additional cloud providers (AWS, GCP, etc.)
+- Container image management
+- Network configuration
+- Volume mounting
+- Resource limits and monitoring
