Just a little UFUNCTION template I like to use.

UFUNCTION TEMPLATE

/**	
 *	My Comment usually goes here.
 *	@param param The input parameter description.
 *	@return The function result description.
 */
UFUNCTION(BlueprintCallable, Category = "MY FUNC"
	meta(DisplayName = "MY FUNC", ShortTooltip = "MY TOOLTIP"))
FString MyFunc(float param);
