-**Alerts (info/warning boxes)**: Use [Docsy alert shortcodes](https://www.docsy.dev/docs/content/shortcodes/#alert)
+**Alerts (note/warning/critical boxes)**: There are three alert types available based on the importance of the information:
+
+| Alert type | Code              | Alert color |
+|------------|-------------------|-------------|
+| Note       | `color="primary"` | Blue        |
+| Warning    | `color="warning"` | Yellow      |
+| Critical   | `color="danger"`  | Red         |
+
+Make sure not to change the title of the alert type. It should always be either Note, Warning or Critical.
