It really wasn't that hard. I followed the advice from Trisha Dunbar in this article https://medium.com/new-era/create-an-index-to-showcase-your-top-stories-e115499bae76. I modeled it off of Jennifer Dunne's index (she said it was OK - : )) https://jennifer-dunne.medium.com

You want to keep the topic pages unlisted so they don't show up in everyone's recommendation feed. Thanks to Jennifer for that tip. With help from the article and a sample index, I got it done. It was on my to-do list for about a month. : )
