Instructions are very sparse about using learnyounode run to test #3
Description
This has come up several times over the last few bmore nodeschool events, where students are generating their own test input to test their lesson files.
It's not so much a big deal when you're just adding up cli args, but I've also seen a number of students generating test files to count new lines as well, and causing themselves more frustration by providing bad input (or differing input than what learnyounode verify expects)
This may not require code change, but maybe in the introduction of the class, go over learnyounode --help command?
