Erlang Tutorial

All you need to get started with Erlang

It's a way to learn Erlang for people who have basic knowledge of programming in imperative languages (such as C/C++, Java, Python, Ruby, etc) and may or may not know functional programming (Haskell, Scala, Erlang, Clojure, OCaml...). I also want to have this guide in a honest manner, selling Erlang for what it is, acknowledging its weaknesses and strengths.
