+### Image paths
+
+When referencing images, you can use either relative paths (`./` or `../`) or paths relative to the root of the `fern` folder by using `/`. For example, if you have an image at `fern/assets/images/overview.png`, you can reference it from any page using `/assets/images/overview.png`:
+
+```markdown
+![Overview](/assets/images/overview.png)
+```
+
+This is equivalent to using a relative path like `../../assets/images/overview.png`, but is more concise and doesn't depend on the current page's location in the folder structure.

 ## Embedding local assets
 
 You can embed local assets in your Markdown pages using the [`<embed>` component](/learn/docs/content/components/embed). This is useful for displaying PDFs, images, videos, OpenAPI files, and other assets into your docs.
