# Markdown Extensions

## Directory Index Customisation

By default, directories without an `index.md` get an auto-generated index page listing their contents.

If you create your own `index.md` in a directory, you can still include the auto-generated file list by using the `{{LIST}}` placeholder:

```md
# Blog

This is my blog. The posts are below. The top-most one is the most recent.

{{LIST}}
```
The `{{LIST}}` placeholder is replaced with the autogenerated file list.

## Table of Contents

`{{TOC}}` auto-generates a nested heading list with clickable anchors.

## Footnotes

Full support for `[^id]` footnotes and `[^id]: text` definitions. They render as a numbered `<section>` at the bottom 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.
