+# IP Information Lookup Tool (iPilot)
+
+This Go application takes an IP address or domain name and gathers the following information:
+- Location
+- Timezone
+- Internet Service Provider
+- Autonomous System
+- Advertised Prefixes

+## Running the script
+Here are some ways that you can run the script:
+| Command                | Description                              |
+| ---------------------- | ---------------------------------------- |
+| `./iPilot -i me`         | Run against your own connection          |
+| `./iPilot -i 1.1.1.1`    | Run against the IP address `1.1.1.1`     |
+| `./iPilot -i google.com` | Run against the domain name `google.com` |
+| `./iPilot -i google.com -p` | Run against the domain name `google.com` and lists BGP prefixes |
+
+## Credits
+This script runs thanks to the APIs provided by [IP-API](http://ip-api.com) and [HackerTarget](https://hackertarget.com/as-ip-lookup).
