Nope. Just a result of human error. Read below for your answer. :)
I'll save you some time here. The answer is as follows:
I went to your site and see what you did wrong.
You copied the text from the readme file and included the comments I had in the readme (that were not supposed to be included on the page but were only for illustration in the readme.)
You're only supposed to copy the PHP lines of code (as per the instructions).
So when you copied the information you also copied the commented text directly from the text file. When you do this with any text, and add it to a file that will be put to the internet, it will render as text on the page (as is in your case).
To remove it, just remove the lines of code that you didn't need in the first place and only include the PHP portions. That will remove it from your site.
