+To integrate Hunter.io API integration into Sn1per, edit your ~/.sniper.conf file and enter the appropriate value for the following:
+
+```
+# HUNTER.IO API KEY
+HUNTERIO_KEY=""
+```
+
+These can be found by logging into your Hunter.io account and viewing the API key from your profile settings. 
+
+In addition, it is also recommended to add your Hunter.io API key directly to theHarvester by editing your /usr/share/theharvester/discovery/huntersearch.py file and adding your API key (this should look similar to below).
+
+```
+vim /usr/share/theharvester/discovery/huntersearch.py
+Update self.key = "your_api_key_here"
+```
+
+Note: Hunter.IO integration only works under "recon" mode scans (ie. -re switch):
+
+Example Usage:
+```
+sniper -t example.com -re -w example.com 
+```
