+# VM Handler Example
+
+This example demonstrates how to use the HandlerFactory with a VM handler to process heroscript commands.
+
+## Overview
+
+The VM handler example shows how to:
+
+1. Create a handler that processes VM-related actions
+2. Register the handler with the HandlerFactory
+3. Start a telnet server that uses the HandlerFactory to process commands
+4. Connect to the telnet server and send heroscript commands
+
+## Running the Example
+
+To run the example:
+
+```bash
+cd ~/code/github/freeflowuniverse/herocode/heroagent/pkg/handlerfactory/cmd/vmhandler
+go run . tutorial
+#to run just the server do
+go run . 
+#you can then go to other terminal and play with telnet / nc
+```
+
+This will start a telnet server on:
+- Unix socket: `/tmp/vmhandler.sock`
+- TCP: `localhost:8024`
+
+## Connecting to the Server
+
+### Using Unix Socket
+
+```bash
+nc -U /tmp/vmhandler.sock
+```
+
+### Using TCP
+
+```bash
+telnet localhost 8024
+```
+
+## Authentication
+
+When you connect, you'll need to authenticate with the secret:
+
+```
+!!auth secret:1234
+```
+
+## Available Commands
+
+Once authenticated, you can use the following commands:
+
+```
+!!vm.define name:'test_vm' cpu:4 memory:'8GB' storage:'100GB'
+!!vm.start name:'test_vm'
+!!vm.stop name:'test_vm'
+!!vm.disk_add name:'test_vm' size:'50GB' type:'SSD'
+!!vm.list
+!!vm.status name:'test_vm'
+!!vm.delete name:'test_vm' force:true
+```
+
+## Example Session
+
+Here's an example session:
+
+```
+$ telnet localhost 8024
+Connected to localhost.
+Escape character is '^]'.
+ ** Welcome: you are not authenticated, provide secret.
+!!auth secret:1234
+
+ ** Welcome: you are authenticated.
+!!vm.define name:'test_vm' cpu:4 memory:'8GB' storage:'100GB'
+VM 'test_vm' defined successfully with 4 CPU, 8GB memory, and 100GB storage
+
+!!vm.start name:'test_vm'
+VM 'test_vm' started successfully
+
+!!vm.disk_add name:'test_vm' size:'50GB' type:'SSD'
+Added 50GB SSD disk to VM 'test_vm'
+
+!!vm.status name:'test_vm'
+VM 'test_vm' status:
+- Status: running
+- CPU: 4
+- Memory: 8GB
+- Storage: 100GB
+- Attached disks:
+  1. 50GB SSD
+
+!!vm.list
+Defined VMs:
+- test_vm (running): 4 CPU, 8GB memory, 100GB storage
+  Attached disks:
+  1. 50GB SSD
+
+!!vm.stop name:'test_vm'
+VM 'test_vm' stopped successfully
+
+!!vm.delete name:'test_vm'
+VM 'test_vm' deleted successfully
+
+!!quit
+Goodbye!
+Connection closed by foreign host.
+```
+
+## Other Commands
+
+- `!!help`, `h`, or `?` - Show help
+- `!!interactive` or `!!i` - Toggle interactive mode (with colors)
+- `!!quit`, `!!exit`, or `q` - Disconnect from server
+
+## How It Works
+
+1. The `main.go` file creates a HandlerFactory and registers the VM handler
+2. It starts a telnet server that uses the HandlerFactory to process commands
+3. When a client connects and sends a heroscript command, the server:
+   - Parses the command to determine the actor and action
+   - Calls the appropriate method on the VM handler
+   - Returns the result to the client
+
+## Extending the Example
+
+You can extend this example by:
+
+1. Adding more methods to the VM handler
+2. Creating new handlers for different actors
+3. Registering multiple handlers with the HandlerFactory
