+# PACKET SNIFFER
+
+Hi all! This is a packet sniffer in python.
+
+## Libraries
+I have used ```scapy``` library
+
+## Getting started
+1. First of all - 
+```
+pip install requirements.txt
+```
+
+2. Secondly - 
+```
+python main.py
+```
+OR
+```
+sudo python3 main.py
+```
+
+That's all. This is how we can use the packet sniffer.
