 The table-of-contents does not currently contain the imported Markdown headings. This is a technical limitation that we are trying to solve ([issue](https://github.com/facebook/docusaurus/issues/3915)).

+## Available exports
+
+Within the MDX page, the following variables are available as globals:
+
+- `frontMatter`: the front matter as a record of string keys and values;
+- `toc`: the table of contents, as a tree of headings. See also [Inline TOC](./markdown-features-inline-toc.mdx) for a more concrete use-case.
+- `contentTitle`: the Markdown title, which is the first `h1` heading in the Markdown text. It's `undefined` if there isn't one (e.g. title specified in the front matter).
