Another suggestion: Instead of just the verbal description of what to type, how about some sample output to? That wouldn't give away any answers but would help understand what you are looking for. Like when you asked "type text to the terminal" I put 'cat' instead of 'echo'. Sample output would probably have helped me there.

Thanks a lot for your suggestion. I agree 100% with you. I am thinking to provide hints to the users either by giving a link to the source or showing a picture of the results or both.
