 By default Flan Scan runs the following Nmap command:
 
 ```bash
-$ nmap -sV -oX $root_dir$xml_dir/$filename -oN - -v1 $@ --script=vulners/vulners.nse $line
+$ nmap -sV -oX /shared/xml_files -oN - -v1 $@ --script=vulners/vulners.nse <ip-address>
 ```
+The `-oX` flag adds an XML version of the scan results to the `/shared/xml_files` directory and the `-oN -` flag outputs "normal" Nmap results to the console. The `-v1` flag increases the verbosity to 1 and the `-sV` flag runs a service detection scan (aside from Nmap's default port and SYN scans).

 ```bash
 $ docker run -v $(shell pwd)/shared:/shared flan_scan <Nmap-flags>
