+# Virtual Vehicle Simulator
+
+A lightweight vehicle simulator that generates CAN telemetry and sends it to the cloud gateway.
+
+## Overview
+
+This service simulates a connected vehicle (T.Rex) by:
+1. Registering with the manufacturer API to get certificates
+2. Connecting to the gateway via WebSocket with mTLS
+3. Generating and sending CAN frames
+
+## Configuration
+
+| Env Var | Description | Default |
+|---------|-------------|---------|
+| MANUFACTURER_URL | URL for vehicle registration | http://gateway:8077/manufacture/manufacturer |
+| GATEWAY_WS_URL | WebSocket URL for gateway | ws://gateway:8077/session |
+| API_KEY | API key for manufacturer endpoint | - |
+| VIN_PREFIX | Prefix for generated VIN | VIRTUAL |
+| SEND_INTERVAL_MS | Telemetry interval in ms | 1000 |
+
+## CAN Frame IDs
+
+| CAN ID | Description |
+|--------|-------------|
+| 0x100 | Speed |
+| 0x101 | RPM |
+| 0x102 | Battery SOC |
+| 0x103 | Battery voltage |
+| 0x104 | Temperature |
+| 0x105 | GPS latitude |
+| 0x106 | GPS longitude |
+| 0x200 | Door status |
+| 0x201 | Light status |
+| 0x300 | HVAC |
