Lean verified a proof of a solution to a problem, but was it the same problem as Erdős problem #124?

There we go, so there is hype to some degree.
Is there some good literature to read about lean? First time I’m hearing about it and it seems pretty cool.
Anything in type theory. Lean is fundamentally a strongly typed dependently typed programming language. Start with Haskell and keep going.
