I think the Phoenix/Elixir docs in general are quite good, it's just the lack of years of blogs and stackoverflow q&a that makes it harder to jump in. Switching from Ruby's OO/functional to Elixir's purely functional/immutable/actor-based would be easier with more of other people's code to read and learn from.

I'm a complete n00b and was just trying to get a pool of TCP client workers to monitor servers and update a DB and display the results in a Phoenix app, and I kept coming across the same 4-6 blog posts and docs, maybe 60% of which were for pre-1.0 Elixir and no longer quite worked.

I see a huge amount of promise with Elixir/Phoenix as well; currently it makes some hard things easy but also many easy things hard. With a few years of library/community growth I could see it wiping the floor with Rails for a lot of projects.
