                Helpful Resources for learning Elixir/Ecto/Phoenix
              
          
    Books & in depth resources


Phoenix Guides - This is one the best ways to get started. The guides cover most of the fundamental topics and explain the ins and outs of how Phoenix works. I would start here and look up the parts of Elixir you don't understand as you go.
Programming Phoenix - Still in beta, but very well done. I would recommend getting it even while in beta. It has a brief introduction to Elixir and covers all the important concepts in Phoenix
Elixir Getting Started Guide - This is the official Elixir getting started guide. You don't need to know everything here to get started, but it covers a lot of fundamentals in sections 1-21.

Specific Phoenix Guides that are very helpful


routing - Covers the router and pipelines
