 - Components that already have matching JS will show that in the Inspector.
 
+## My custom TypeScript component doesn't show up in the Unity/Blender component menu
+
+Make sure your script is located inside the web project's `src/scripts` folder. The Needle component compiler only picks up scripts in this folder to generate the matching Unity stub components / Blender component panels — components placed elsewhere won't appear in Unity's or Blender's component menu.
