Here are some extended Markdown features supported by Retypeset, including syntax examples and their stylistic effects.
## Figure Captions
To create automatic figure captions, use the standard Markdown image syntax ``. To hide the caption, add an underscore `_` before the `alt` text or leave the `alt` text empty.
### Syntax
```
```
### Output
## Github Repository Cards
To create a Github repository card, use the double colon syntax `::github{repo="owner/repo"}`. Repository data is fetched in real-time from the GitHub API after the page loads.
### Syntax
```
::github{repo="radishzzz/astro-theme-retypeset"}
```
### Output
::github{repo="radishzzz/astro-theme-retypeset"}
## Admonition
To create admonition blocks, use the GitHub syntax `> [!TYPE]` or the triple colon syntax `:::type`. Following types are supported: `note`, `tip`, `important`, `warning`, and `caution`.
### Syntax
```
> [!NOTE]
> Useful information that users should know, even when skimming content.
