+## NAME
+
+ronin-nmap-new - Generates a new nmap ruby script
+
+## SYNOPSIS
+
+`ronin-nmap new` [options] *FILE*
+
+## DESCRIPTION
+
+Generates a new nmap scanner or parser Ruby script that uses the `ronin-nmap` 
+library.
+
+## ARGUMENTS
+
+*FILE*
+: The path to the new Ruby script to generate.
+
+## OPTIONS
+
+`--parser`
+: Generates a new nmap XML parser Ruby script.
+
+`--scanner`
+: Generates a new nmap scanner Ruby script.
+
+`--printing`
+: Adds additional code to the Ruby script that prints the nmap XML scan data.
+  Is compatible with both `--parser` and `--scanner`.
+
+`--import`
+: Adds additional code to the Ruby script that imports the nmap XML scan data.
+  Is compatible with both `--parser` and `--scanner`.
+
+`--xml-file` *XML_FILE*
+: Parses or writes the scan results to the given XML File.
+  Is compatible with both `--parser` and `--scanner`.
+
+`-p`, `--port` {*PORT* \| \[*PORT1*\]-\[*PORT2*\]},...
+: Specifies the ports to scan. Not compatible with the `--parser` option.
+
+`--target` *TARGET*
+: Adds a target to scan. May be a host name, IP, IP CIDR range (ex:
+  `192.168.1.1/24`), or IP glob range (ex: `192.168.*.1-4`).
+  Not compatible with the `--parser` option.
+
+`-h`, `--help`
+: Print help information
+
+## EXAMPLES
+
+Generates a new nmap scanner Ruby script that scans `example.com`, ports 22, 80,
+443, and 8000 through 9000:
+
+    $ ronin-nmap new scanner.rb --ports 22,80,443,8000-9000 --target example.com
+
+Generates a new nmap XML parser script that parses `path/to/nmap.xml` and prints
+the scan information.
+
+    $ ronin-nmap new parser.rb --parser --xml-file path/to/nmap.xml --printing
