+# Network Scanner
+
+This is a simple Python script that uses the Scapy library to scan the local network and find connected devices.
+
+## Usage
+
+1. Install the Scapy library. You can install it using pip:
+
+   ```shell
+   pip install scapy
+
+2. Run the script by executing the following command:
+
+   ```shell
+   python network-scanner.py
+
+3. When prompted, enter the target IP address or IP range in the format "ip_address/24". For example, "192.168.1.0/24".
+
+4. The script will send ARP requests to the specified IP range and display the list of available devices along with their IP and MAC addresses.
