Get mentored the Ruby way

Every language has its own way of doing things. Ruby is no different. Our mentors will help you learn to think like a Ruby developer and how to write idiomatic code in Ruby. Once you've solved an exercise, submit it to our volunteer team, and they'll give you hints, ideas, and feedback on how to make it feel more like what you'd normally see in Ruby - they'll help you discover the things you don't know that you don't know.
