Same comment re 'instructions': use

The left panel contains explanations and guides to run Unix commands. Use the right panel to type command examples and experiment as you wish. Unix commands for you to execute will appear in the left panel on a grey background (like this example): they must be typed in the right panel. You may modify them, but in order to answer questions or quizzes, we advise you to copy the proposed instructions exactly as they are.
