Sorry, I posted the issue to find out if that was the correct way to say it and from what people wrote I got the impression that it was and I was encouraged to make a pull request. I can't find those people's comments anymore, so I can't point to anything specific.

Since I don't have a good idea of what's really going on, I don't feel comfortable making a pull request. Perhaps in future this section of the instructions could include an explanation of what makes up a command-line argument and what the rest of the words on the command-line are? If this is geared for beginners I can tell you, as a beginner, that the nature of what is written in the command line is not very clear right now.
