 ## Overview
 
-The IGMP Packet Generator is a specialized tool designed for generating various types of Internet Group Management Protocol (IGMP) packets. This tool is particularly useful for network administrators, developers, and researchers involved in testing and analyzing network protocols, multicast networks, and network security systems.

 ## Features
 
-- **Multiple IGMP Versions Support**: Supports different IGMP versions, including IGMPv1, IGMPv2, and IGMPv3.
+* **Support for Multiple IGMP Versions**: Compatible with IGMPv1, IGMPv2, and IGMPv3.
-- **Various IGMP Packet Types**: Capable of generating different types of IGMP packets, such as Query, Report, and Leave messages.
+* **Variety of IGMP Packets**: Capable of generating Query, Report, Leave, and other IGMP packet types.
-- **Customizable Packet Parameters**: Allows customization of various packet parameters like source and destination IP addresses, ports, and group addresses.
+* **Customizable Packet Parameters**: Allows setting of source/destination IPs, ports, and multicast groups.
-- **Router Alert Option**: Includes support for the Router Alert IP option (IPOPT_RA).
+* **Router Alert Option**: Implements the Router Alert IP option (IPOPT_RA).
 
 ## Requirements
 
-- A Unix-like operating system.
+* Unix-like operating system.
-- `libnet` library installed for packet crafting and network handling.
+* `libnet` library
+* CMake for building the project.
 
-## Installation
+For debian/ubuntu, simply type:
 
-1. Ensure that the `libnet` library is installed on your system.
+```shell-session
-2. Compile the source code using a C compiler. For example:
+sudo apt-get install cmake libnet1-dev
-
-```bash
-gcc -o igmp_packet_generator igmp_packet_generator.c -lnet
 ```
 
-3. Run the compiled binary to start generating IGMP packets.
+## Install
+
+### Clone the Repository (if applicable):
+
+```bash
+git clone [repository-url]
+cd igmpgen
+```
+
+### Build with CMake:
+
+Create a build directory:
+
+```shell-session
+mkdir _build && cd _build
+```
+
+Run CMake and build the project:
+
+```shell-session
+cmake ..
+cmake --build .
+```
+
+### Install binaries
+
+```shell-session
+cmake ..
+cmake --install .
+```
 
 ## Usage
 
-To use the IGMP Packet Generator, run the compiled program with the necessary command-line arguments:
+After building, you can run `igmpgen` with the necessary command-line arguments:
-
-```bash
-./igmp_packet_generator -i [interface] -g [group] -t [version.packet_type] [-s [src_ip:port]] [-d [dst_ip:port]]
-```
 
 ### Command-Line Arguments
 
-- `-i [interface]`: Specify the network interface to use (e.g., `eth0`).
+```bash
-- `-g [group]`: Specify the multicast group IP address.
+IGMP packet generator
-- `-t [version.packet_type]`: Define the IGMP version and packet type (e.g., `2.query` for an IGMPv2 Query).
+
-- `-s [src_ip:port]`: (Optional) Set the source IP address and port.
+Usage: ./igmpgen [options]
-- `-d [dst_ip:port]`: (Optional) Set the destination IP address and port.
+
+Options:
+  -i <interface>   Specify the network interface (e.g., eth0)
+  -t <type>        Specify the IGMP packet type and version (e.g., 1.query)
+  -g <group>       Specify the IGMP group (e.g., 224.0.0.1)
+  -s <source>      Specify the source IP and port (e.g., 192.168.1.1:1234)
+  -d <destination> Specify the destination IP and port (e.g., 224.0.0.2:5678)
+  -n <number>      Specify delay between packets in seconds (optional)
+
+Available IGMP packet types:
+ - 1.query
+ - 1.report
+ - 1.dvmrp
+ - 2.query
+ - 2.report
+ - 2.leave
+ - 3.report
+```
 
 ### Example
 
-To generate an IGMPv2 Membership Report for the group `224.0.0.1` on `eth0`:
+Generate an IGMPv2 Membership Report for group `224.0.0.1` on `eth0`:
 
 ```bash
-./igmp_packet_generator -i eth0 -g 224.0.0.1 -t 2.report
+./igmpgen -i eth0 -g 224.0.0.1 -t 2.report
 ```
