If you were to contribute to rails today, and you knew nothing about rails,

How would you exactly go about it?

1. Learn Ruby to a good level where you can understand (almost) any ruby code? if yes, is there any tutorial or book you recommend?

2. Learn Rails to understand all the different parts of it?

3. Or would you just go on and start reading the rails quick start guide, and then get immediately to reading all of the issues on github and start contributing to the docs first and work your way up from there?

Thanks :)
