+# USB HID Validation
+
+## Overview
+
+This shell script executes on the DUT (Device-Under-Test) and verifies enumeration of connected USB Human Interface Devices (HID).
+
+---
+
+## Setup
+
+- Connect USB HID peripheral(s) to USB port(s) on DUT.
+- Only applicable for USB ports that support Host Mode functionality. 
+- USB HID peripherals examples: Mouse, Keyboard, USB headset, etc. 
+
+---
+
+## Usage
+### Instructions:
+1. **Copy the test suite to the target device** using `scp` or any preferred method.
+2. **Navigate to the test directory** on the target device.
+3. **Run the test script** using the test runner or directly.
+
+---
+
+### Quick Example
+```bash
+git clone <this-repo>
+cd <this-repo>
+scp -r common Runner user@target_device_ip:<path-on-device>
+ssh user@target_device_ip
+cd <path-on-device>/Runner && ./run-test.sh usb_hid
+```
