 How do we commoditize or make Kubernetes more easy to learn and approach, right? So that's where we run into Cuba example and one of the things that we've been trying hard internally is that our focus was only based on can we put some examples out there, can we have some communities out there. And what Cuban example allows us to do is that it is focused, white-sized, five-minute concepts that are packaged and you can actually go learn about these things in small packets of things rather than just saying that hey I'm going to carve out my entire Friday three hours and Friday and learn Kubernetes in couple of Fridays, right? So the beauty of tools and efforts in the community like Cuba example is like it packages all these different concepts into more easily digestible morsels that you can consume at will without actually trying to say that I'm going to invest hours together into it in one fell swoop.
