+## Overview
+
+This Python script allows you to perform a ping sweep on a range of IP addresses within a specified subnet to identify live hosts. It supports both Windows and Unix-like systems for the ping command.
+
+## Features
+
+- Scan a range of IP addresses within a subnet.
+- Detect live hosts within the specified range.
+- Cross-platform compatibility (Windows and Unix-like systems).
+
+## Usage
+
+1. Run the program
+
+   * For Windows (Powershell/CMD): 
+
+      ```
+      python main.py
+      ```
+
+   * For Linux (bash/zsh/unix):
+
+      ```bash
+      sudo python3 main.py
+      ```
+
+   `Root privilege is required for linux users, as modern kernels of linux don't allow pinging without root privilege.`
+
+2. Follow the on-screen instructions to provide the following information:
+
+   * Subnet IP (e.g., 192.168.0)
+   * Starting IP range
+   * Ending IP range
+
+## Example
+
+```
+Enter the SUBNET IP: 192.168.1
+Enter Starting Range: 1
+Enter Ending Range: 10
+```
+The script will scan the hosts ranging from IP Address: 192.168.1.1 to 192.168.1.10.
+
+```
+Scanning completed in 0:00:13.741418
+
+Live Hosts:
+192.168.1.1 --> Live
+192.168.1.2 --> Live
+192.168.1.5 --> Live
+192.168.1.7 --> Live
+192.168.1.9 --> Live
+```
+
+---
+
+`The efficiency of the program solely depends on factors such as network traffic and connectivity of devices to the router/dhcp server. Also, in some cases, the program skips some live hosts, even though they're up due to delay in responding to the ping command within the time slot.`
