Do I still need lightmaps?

I am currently following the “Project: Stealth” tutorial but in the first video I am presented to work with lightmaps but the Unity 5 UI doesnt match the guy’s UI from the video… I know that this is because the new changes in Unity 5 with the GI and all that but i dont know if I still have to do some baking or I should have Realtime Baking checked… I am really confused. Can somebody help me directly with this tutorial please?
Thank you very much !

i Think you should use the normal setting and then bake, unless the guy edits some settings that are deprecated from Unity 5 then a problem with lighting may appear
