I generally agree that -in the absence of sufficient documentation- reading the tests and source for the project is generally the best way to learn how to use a project.

However. If the language the project is written in is wildly unfamiliar to you, and you've never had experience with a similar language, then this technique is often... less than satisfying.

From your comments, it appears that you have more than a passing familiarity with Erlang/OTP. You have to admit that it would be substantially harder to understand both Elixir and Phoenix without your understanding of Erlang. :)
