+
+```bash
+pip3 install dnspython
+```
+
+## Usage

+To use the DNS explorer, run the script with the desired command-line arguments:
+
+```bash
+python dns_explorer.py -d <domain> -f <subdomain filepath>
+```
+or 
+```bash
+python dns_explorer.py -ip <ip_address>
+```
+
+Example:
+```bash
+python dns_explorer.py -d example.com -f subdomains.txt
+```
+or 
+```bash
+python dns_explorer.py -ip 8.8.8.8
+```
+
+## Command Line Arguments
