**text**or__text__ - Italic:
*text*or_text_ - Bold + Italic:
***text*** - Ordered lists: Lines starting with
1.,2., etc. - Unordered lists: Lines starting with
-,*, or+ - Links:
[text](url) - Images:
 - Blockquotes: Lines starting with

---,***, or___ - Inline code:
`code` - Fenced code blocks: Triple backticks with optional language for syntax highlighting
Syntax Highlighting
Fenced code blocks support language-specific highlighting via highlight.js. Specify the language after the opening backticks:
```javascript
const greeting = "Hello, world!";
```
GFM Extensions

Footnotes
Reference footnotes inline with [^1] and define them anywhere in the document:
This has a footnote[^1].
[^1]: The footnote content appears at the bottom.
Autolinks
URLs are automatically converted to clickable links without needing [text](url) syntax.
Emoji Shortcodes
Use :emoji_name: to insert emoji. For example, :smile: renders as a smiley face, :rocket: renders as a rocket.
