Add a "how it works" page or section to the website. 

This should explain at a high level
* How the API works - every run is independent. You upload the code for the run and away you go.
* How Yinyo itself runs on a Kubernetes cluster and submits the stuff to Kubernetes which then runs the scrapers across a cluster of machines.

This should probably go at the bottom of the current home page. It should also have a few illustrations
