This is a document I’ve been sharing with friends for a couple of years, which I have “sanitized”, as in replacing real addresses with documentation addresses, updating the diagrams for a general audience, and generally proof-read.
Access it at the Google Doc:

I will be grateful if you report issues with the doc, to my email which is in the heading.
