+## Description
+
+The “udp_sweep” module scans across a given range of hosts to detect commonly available UDP services.
+
+## Verification Steps
+
+1. Do: ```use auxiliary/scanner/discovery/udp_sweep```
+2. Do: ```set RHOSTS [IP]```
+3. Do: ```set THREADS [number of threads]```
+4. Do: ```run```
+
+To configure this module, just set the RHOSTS and THREADS values and run it.
+
+## Scenarios
+
+**Running the scanner**
