you can do custom documentation on classes and properties by using .udn files. This is what is used when in the tooltip you see “Hold (Ctrl + Alt) for more”.

How to use

(Thanks to Hojo)

  1. Get a template from UE_5.X\Engine\Documentation\Source\Shared. For example UE_5.X\Engine\Documentation\Source\Shared\Types\UActorComponentUActorComponent.INT.udn
  2. Use a toll such a VSCode to have a live markdown preview.
  3. Put the file in your project/plugin Documentation folder
