+## Theme Custom Shortcodes
+
+These shortcodes are not Hugo built-ins, but are provided by the theme.
+
+### Responsive Images with Cloudinary
+
+You can learn more about this [here](https://cloudinary.com/documentation/responsive_images).
+
+Set the `cloudinary_cloud_name` parameter in your site config to use this shortcode.
+
+```
+{{</* dynamic-img src="/my/image/on/cloudinary" title="A title for the image" */>}}
+```
+
+Note that you do not include the file extension (e.g. `.png`) in the `src` parameter, as the shortcode will automatically determine the best quality and format for the user's device.
+
+Optionally, you can customize the general CSS styles for the image:
+
+```
+{{</* dynamic-img src="/my/image/on/cloudinary" title="A title for the image" style="max-width:60%" */>}}
+```
