+# Pinger
+
+**Pinger** is a lightweight, high-performance network utility written in Go. 
+It enables users to send ICMP echo requests (pings) to specified hosts, facilitating network diagnostics and monitoring.
+
+## Features
+
+* Send ICMP echo requests to specified hosts.
+* Measure round-trip time (RTT) for each ping.
+* Support for both IPv4 and IPv6 addresses.
+* Configurable number of ping attempts and intervals.
+* Lightweight and efficient, suitable for scripting and automation.
+
+## Installation
+
+### Prerequisites
+
+* Go (version 1.20 or later) installed on your system.
+* make
+
+### Steps
+
+1. Clone the repository:
+
+```bash
+git clone https://github.com/pnx/pinger.git
+cd pinger
+```
+
+2. Build the application:
+
+```bash
+make
+```
+
+## Usage
+
+See `./pinger -h`
+
+### Example
+
+```bash
+./pinger --udp -t 30s example.com
+```
+
+This command sends UDP echo requests to example.com, stopping after 30 seconds
+
+```bash
+./pinger -c 8 -i 1s example.com
+```
+
+This command sends 8 ICMP echo requests to example.com, with a 1-second interval between pings.
