+## What is Metabigor?
+Metabigor is Intelligence Framework, its goal is to do OSINT tasks and more but without any API key.
+
+
+## Installation
+
+```
+go get -u https://github.com/j3ssie/metabigor
+```
+
+
+### Example Commands
+
+```
+# discovery IP of ASN
+echo "company" | metabigor net --org -o /tmp/result.txt
+
+# discovery IP of ASN
+echo "ASN1111" | metabigor net --asn -o /tmp/result.txt
+cat list_of_ASNs | metabigor net --asn -o /tmp/result.txt
+
+# running masscan on port 443
+echo "1.2.3.4/24" | metabigor scan -p 443 -o /tmp/result.txt
+
+# running masscan on port all port and nmap on open port
+cat list_of_IPs | metabigor scan --detail -o /tmp/result.txt
+```
