In the middle of page 7, the paragraph starts with, “From the Windows start screen you’ll be launch your preferred terminal…”. I’m guessing that you mean it only to say “you’ll launch…”

Also, at the end of the paragraph, it says to verify the Ruby installation by “entering the command ruby -v as follows:”, which is followed by a window showing a search for “ruby”, with a suggested result of “Start Command Prompt with Ruby”. It does not show an actual terminal where “ruby -v” was entered and run. Was this intentional?
