 ## Markdown guide
 
 Academic Pages uses [kramdown](https://kramdown.gettalong.org/index.html) for Markdown rendering, which has some differences from other Markdown implementations such as GitHub's. In addition to this guide, please see the [kramdown Syntax page](https://kramdown.gettalong.org/syntax.html) for full documentation.
