Can not start: "(Koans.MeditateWarning) Please meditate: you should start a ExUnit server to automatically run your test case" #21

I am fairly new to Elixir so I might be missing something obvious, but I can not start any koan from the repository.

Hi, of course, it's koans: an exercise to understand basic features about elixir. You have to replace "__" by values in tests files. Meditate Warning indicate the place where you have to change the code and what you have to do.

Oh, makes sense. I didn't know what a koan meant, just looked it up. :P

I think the term koan was first coined in ruby. We've not pushed the logic too much here, it's just small exercises to discover few features of elixir. In fact I started to wrote it for an informal workshop with friends to discover elixir, just in case to have a support, so it is far to be finished and it is maintained just the minimum.
