I have made an improved version of the recipe.
I removed the Javascript message, as well as the bullet points after the title and the "Related" section at the bottom of the article, just leaving the main text. I could not, however, keep the article author's name.
I set a masthead URL so we get the logo at the top of the Sections menu and fixed the feed URLs (there were http instead of https URLs, as well as the Life feed being wrongly set to the Opinion feed URL. I added the Top Stories feed, too.
I went ahead and made a pull request with the updated recipe:
