I would make this a bullet-pointed list of each step after "therefore", I think it will highlight what you're saying nicely.

Good idea, thanks Baris!

Pretty sure Elixir is now a supported language.

Not really getting the meaning of this sentence Many common things that you will be using live inside modules like the Integer module we showed above. I think you showed one thing (digits) so it's a bit confusing.

Hm..I see you what you're saying Kriszta. I wanted to stay consistent with the theme of functions seen as actions. Would something like this be better: Many common actions that you will be using on different data, often live inside modules that are associated with that data or is this still confusing?

Spotted a few minor things, mostly typos here and there. This looks really great otherwise!

I'm going to close this PR as it's very old, I'd still very much be interested in an Elixir tutorial for our blog though in our tech section https://medium.com/the-codelog |

Hey everyone 馃槂
This is an initial draft for adding the Elixir tutorials and to get some thoughts/feedback from the community.
The roadmap is the following:
I also wanted to explain my approach with these tutorials which is based on personal experience, both at teaching at Codebar as well as my own apprentices at 8th Light. It's also influenced by this blog post. The goal is to have small tutorials that cover one new concept at a time. This enables the student to achieve small wins and reinforce the feeling of achievement more frequently.
What would be nice is if we can think of an exercise which can be broken down into sections where each section is covered in one of the above lessons and at the end the student ends up building a nice little project that would otherwise be too big to complete in one lesson.
Any feedback on any of the above would be great 馃槂
