It's a not a new exercise for tough guys. It's a command for Unix users, "man curl". The command is "curl" and "man" shows you the manual or "man page" for that command. The "curl" command is used to pull down remote files to a local directory via the command line. It's an important command to know if you are a Mac OS and Unix user. For Windows/Powershell users there is the Invoke-RestMethod command.
