I can't find ai category?

Im happy that the website for AI tutorials had been fixed but I am a bit stuck in ai category from this weblink https://docs.unrealengine.com/latest/INT/Engine/AI/BehaviorTrees/QuickStart/4/index.html

I just finish all tutoial but AI do not follow player, that why I believe I’ve skip AI category part.
