This is where I started with Erlang, learned it first then leaned Elixir. I really enjoyed working with Erlang/Elixir & OTP.

I’d agree with previous suggestions, either this book or Joe Armstrong’s.

+1 Fred's book is great -- I learned Erlang using it

+100! The whole book is online for free and I've found it explains things in a very plain and friendly way.

I also really love this book! I'd also add that Adopting Erlang[1] is a great resource.
