@@ -20,13 +20,3 @@ Frames should be ordered where frame children come first, followed by the frame
 ```
 
 If not oredered correctly, the editor will still function, but the elements may not be rendered and clipped correctly. Further, the renderer relies on this ordering for performance optimizations.
-
-# Arrows
-
-An arrow can be a child of a frame only if it has no binding (either start or end) to any other element, regardless of whether the bound element is inside the frame or not.
-
-This ensures that when an arrow is bound to an element outside the frame, it's rendered and behaves correctly.
-
-Therefore, when an arrow (that's a child of a frame) gets bound to an element, it's automatically removed from the frame.
-
-Bound-arrow is duplicated alongside a frame only if the arrow start is bound to an element within that frame.
