@JohnStrunk - I threw#219 up there as an example which is based on what they did with community operators - so I like the big warning image - so it's obvious to users, maybe add that in?

and I think it would be beneficial to remove the rest of the readme...don't even give them a chance to read anything about the project until they click to the new link

And then after the final switch we can just archive as read-only

[screeley44]

I'd do the same with helm readme and the index.rst - IMHO

[JohnStrunk]

I adjusted the main + helm readme, and I also added a banner to all the docs pages.

@screeley44 I think this is ready for another look
