Recommend deleting first header
I think it's better to have introductory text before the first header on a page. It seems to me that the text under the first header "Maximizing..." works well enough on this page without the header. Just a suggestion.
Thanks for your feedback. I agree, intro text before a heading is good practice. However, with the new snapshot approach where we generate a page for a static website, the level one heading replaces the page title in the snapshot view, hence the deviation from our usual practice.
