syzygy request for info

Hi,
I just started to study syzygy table base code to understand how it work.
I started reading probe code of stockfish which partially documents the decode/uncompress functions.
As far as I have understood syzygy is a complex compression algorithm able to give good compression and fast enough probe speed.
In addition to Ronald and stockfish code do you know if format or some kind of documentation or paper is available to study it?
Thank you all

Ronald's site on github appears to be gone now.
Maybe he bugged out because Microsoft bought it.
This might be useful:
https://github.com/basil00/Fathom
It is a demonstration interface to the syzygy TB code.

Search me, the search is broken.

thank you all,
the sites you gave me are implementation of syzygy TB, do you know any kind of codumentation regarding syzygy? I know there is a thread here on talkchess between costalba e de man where Marco asked questions to ronald when he started rewriting stockfish code, and I'm reading it

You're searching for a repository called syzygy. Ron's account is "syzygy1", and the repository name is "tb".
The users tab brings up syzygy1 as the 3rd result.

Maybe so, but that search used to work.
Something either got broken, or got fixed.

There is no single document or paper that explains everything (except for the source code).
What do you want to know/where do you get stuck?
