+Custom editor icon
+------------------
+By default, Godot uses the node icon in the scene dock for GDExtension nodes. The custom icon can be
+added via the ``gdextension`` file. The node's icon is set by reference to its name and resource path
+of an SVG file.
+
+For example:
+
+.. code-block:: none
+
+    [Icon]
+    GDExample = "res://icons/GDExample.svg"
+
+The path should point to a 16 by 16 pixel SVG image. Read the guide for :ref:`creating icons <doc_editor_icons>`
+for more information.
