+Tips for sidenotes.
+
+<!--more-->
+
+## Sidenotes
+
+[LaTeX.css](https://latex.vercel.app/), which HugoTeX is using, defines syntax for sidenotes. However, as it is a little verbose to write, we provide a Hugo shortcode for that:
+
+```md
+A sentence deserving a sidenote.{{%/* sidenote */%}}The note itself.{{%/* /sidenote */%}}.
+```
+
+Will render into
+
+---
+A sentence deserving a sidenote.{{% sidenote %}}The note itself.{{% /sidenote %}}.
+
+---
+
+## Tables
+
+Another shortcode allows to insert tables with captions:
+
+```md
+{{< table title="A sample table with a descriptive caption via [LaTeX.css](https://latex.vercel.app/)." >}}
+| Header 1      | Header 2      | Header 3      |
+|---------------|---------------|---------------|
+| Description 1 | Description 2 | Description 3 |
+| Description 1 | Description 2 | Description 3 |
+| Description 1 | Description 2 | Description 3 |
+|---------------|---------------|---------------|
+| Footer 1      | Footer 2      | Footer 3      |
+{{< /table >}}
+```
+
+Will render into
+
+---
+
+{{< table title="A sample table with a descriptive caption via [LaTeX.css](https://latex.vercel.app/)." >}}
+| Header 1      | Header 2      | Header 3      |
+|---------------|---------------|---------------|
+| Description 1 | Description 2 | Description 3 |
+| Description 1 | Description 2 | Description 3 |
+| Description 1 | Description 2 | Description 3 |
+|---------------|---------------|---------------|
+| Footer 1      | Footer 2      | Footer 3      |
+{{< /table >}}
