+## Source code
+
+Source code for this example can be found [here](https://github.com/flipperdevices/flipperzero-firmware/tree/dev/applications/examples/example_images).
+
+## General principle
+
 To use icons, do the following:
-* add a line to the application manifest: `fap_icon_assets="folder"`, where `folder` points to the folder where your icons are located
-* add `#include "application_id_icons.h"` to the application code, where `application_id` is the appid from the manifest
-* every icon in the folder will be available as a `I_icon_name` variable, where `icon_name` is the name of the icon file without the extension

 So the icons are in the `images` folder and will be available in the generated `example_images_icons.h` file.
