+
+## Table of Contents
+
+You can auto-generate a Table of Contents by placing `{{TOC}}` anywhere in your markdown file. It collects all `h2` and `h3` headings and generates an ordered list with anchor links.
+
+## Footnotes
+
+Footnotes use the `[^id]` syntax inline and `[^id]: text` for definitions at the bottom of the file. They are rendered as a numbered `<section>` at the end of the page.
+
+## Definition Lists
+
+Definition lists use the standard syntax:
+
+```md
+Term
+: Definition
+```
+This renders as `<dl><dt>Term</dt><dd>Definition</dd></dl>`. Multiple definitions per term are supported.
+
+## Emoji Shortcodes
+
+Standard GitHub/MkDocs emoji shortcodes like `:smile:`, `:fire:`, `:rocket:` are automatically replaced with their Unicode emoji equivalents. Shortcodes inside code blocks are left as-is.
