# History
TLA$^+$ stands for Three Letter acronym. It was invented by Leslie Lamport, who notably invented $\LaTeX$. TLA+ is a language for writing and checking specifications. It helps to work on system designs, and to show if a system meets specifications. 

There is a nice [learntla](https://learntla.com/intro/faq.html#what-s-tla) website set up by the community, mostly by Hillel Wayne

TLA stands for 'Temporal Logic of Actions'. It's a formal specification language.

TLA mainly works with a tool called TLC, which is a model checker. TLC is exhaustive, and will check every possible case.
