From the link above, I also found Leslie Lamport's Home page[1], The original developer of TLA+. Leslie's home page contains an incredible amount of info about TLA. There's a published Book with pdf available. There are video courses and talks.

There are also git repos of examples[2] and tools[3]

Thanks for the link, _doctor_love
