ASDF: Extendable version manager with support for Ruby, Node.js, Elixir, Erlang & more
https://github.com/asdf-vm/asdf

Asdf is a tool to manage multiple programming language versions, instead of using rbenv for ruby, pyenv for python, nvm for node, etc. this uses the same syntax to install and maintain multiple programming language versions.

Other Information

I've always used rbenv to setup my ruby dev env (btw this is how I come to know this guide), now I use asdf and it works great, to keep the ball rolling how should we put the asdf instructions and keep the other options like rbenv in ruby?

Asdf -> Ruby / Python / Node...

or

Ruby -> Asdf
Python -> Asdf

ASDF looks really interesting, I would give it a shot but definitely worth adding to the guide.
