Menu in the node editor is different than the one on the tutorial I'm trying to follow I'm trying to reproduce this tutorial on my Blender 2.79 in Linux machine from this YouTube video: https://www.youtube.com/watch?v=K3CwKkiJZN0. But the problem is somewhere in this video, instructor switches to node editor and his screen looks like this:

 

I just draw a red circle over that option that I don't see in my Blender when I switch to node tree. In fact, my Blender looks like this:



As you can see, I don't have that option in my node editor and unfortunately, instructor does not say anything about that option (e.g. how to load it up). I will be very grateful to let me know how I can add that option in my node tree in order to be able to reproduce this tutorial. I really appreciate any comment, suggestion, or recommendation.

Update:

I downloaded v2.0 of animation nodes add on and I enabled it like this:
What you are seeing is an addon called "animation nodes"

It is not installed by default. You would need to download it (do not Unzip the file) and install it using "Install from File"
