With Quick Index you can easily add an index (Table of Contents) to your content. The index will be generated based on the headings in your content.
Simply place {index} where you want the index to show.
You can see Quick Index in action on all the Documentation pages in this Regular Labs website.
Quick Index offers a lot of options, allowing you to control what the index includes and how it looks.
Pro can automatically add indexes, output an index from an article elsewhere, set separate index and heading level ranges, number headings, include parent headings in generated IDs, and remove configured words from IDs.
