+To integrate Censys sub-domain retrieval into Sn1per, edit your ~/.sniper.conf file and enter the appropriate values for the following:
+
+```
+# API KEYS
+CENSYS_APP_ID=""
+CENSYS_API_SECRET=""
+```
+
+These can be found by logging into Censys and viewing the ID and Secret from your profile settings. 
+
+Note: This only works under "recon" mode scans (ie. -re switch):
+
+```
+sniper -t example.com -re -w example.com 
+```
