I would love to contribute to Elixir, but jumping right into Elixir's issue list on Github to fix the bug there is a bit too hard for me. I wish there was some resources getting us familiarized with Elixir code base, and leading us more easily into contributing to Elixir, just like the The Eudyptula Challenge for Linux Kernel (http://eudyptula-challenge.org/). Or is there already this kind of resource?
