I needed to switch & track the multiple Elixir/Erlang versions used in different apps without losing my sanity. Did not want to install multiple managers - one for Elixir, one for Erlang and then Node.js.. So asdf Version Manager to the rescue. It manages versions for all 3 and ruby, postgres etc., Thank you @hashnuke!

I wrote down the steps to setup Elixir, Erlang and Node.js with asdf Version Manager..
