The project README is getting quite large mainly because of all
the getting started guides embedded in the README.
Create the docs/getting-started-guides directory and relocate all
getting started guides. Update the README to link to each getting
started guide.
As I read through it I wanted to wordsmith a bit, which lead to reordering
some to read sort of top-down. There were a couple things I thought were wrong
(pod name should be a subdomain) and a few things I think we can make more
concise. I also added examples and clarified implications.
