Can non ic-system-devloper read this doc?

Im interesting in ic system architecture and code inside.

https://github.com/dfinity/ic/blob/master/rs/README.adoc


It says need to login. but i find no register bottom at the page .

It links to a non-public document. “Fun” fact: As an authorized user I still cannot read the document. It fails with 502 Gateway error

I’ll see if I can get this fixed…
