@ -19,6 +19,8 @@ In the body of the `toc` code widget you can configure a few options:
* `headerText`: by default "# Table of Contents\n". Change it to change the rendering of this header
* `minHeaders`: only renders a ToC if the number of headers in the current page exceeds this number, otherwise renders an empty widget
* `maxHeaders`: only renders a ToC if the number of headers in the current page is below this number, otherwise renders an empty widget
* `minLevel`: only renders a ToC for headers below that level (if you do not want to display e.g. the first header)
* `maxLevel`: only renders a ToC down to this level (e.g. if you have too many sublevels.)
Example:
```toc
