I have read the Adding anchor next to headers thread, but I am at a loss about the most Markdown/Hugo-friendly way to proceed. Any help would be appreciated!
Hugo already auto-generates an ID tag on each heading. I create a Hugo shortcode - layouts/shortcodes/note-heading.html - that generates the header link decorated with the calendar icon from Feather Icons.
Then in my markdown document I use {{< note-heading “A note of interest ” >}} for headers.
