Thomas, we agree on removing this phrase because it doesn't say much -> "The actual code needed to make this all work can vary quite a bit, but here's one example:"

However, we disagree with the removal of the first phrase: "The addFormToCollection() function's job will be to use the data-prototype attribute to dynamically add a new form when this link is clicked.". That's the most crucial phrase to understand what's that "strange" data-prototype attribute, so we left it. However, we included your minor tweaks to the original text.

Thanks!
