I've been writing a lot about Elixir as I've been learning it: https://inquisitivedeveloper.com/. The idea is for people to learn Elixir along with me as I learn it.

It's not a quick start though: I really dig into how Elixir works and move fairly slowly. I've finished covering the language itself, and I'm about to move into the OTP functionality that's inherited from Erlang.
