The above covers the language basics/ideas/concepts and the main tooling (Phoenix/Ecto) if you're looking to build apps or get an Elixir job. I definitely recommend the Phoenix Guides or similar - they're very high quality and kept up to date with any new releases or changes while books can sometimes get out of date.
