 ## How are types represented?
 You're a nosy one, aren't you?
 Elchemy represents all type constructors as snake cased atoms, and all type applications as tuples.

 ## Can I use already existing Elixir libraries with Elchemy?
-Yes. You can do an `ffi` call to any function in any module. Whether it's Elixir module, Erlang module, or even a macro you can include it in your code. Ffi calls are a treated specially in Elchemy and they get generated test to analyze the types based on @specs, so that you don't compromise type safety for using Elixir code. 
-In order to increase readbility it's advised no to use `ffi` calls if not necessary and always document and doctest them.
