The Odin Project is crowdsourced. It is built both by experienced engineers and by people who are currently learning to code. Regardless of your experience, you can contribute. Even if you don't feel ready, you can still get involved and observe until you're comfortable.
Anyone with any experience level can contribute to the curriculum. Students in particular are encouraged to do this, especially if you are just starting out!
The Odin Project is a Ruby on Rails application. As with any Open Source project, there is a constant backlog of outstanding issues and new features. Anyone is welcome to join in and start working on any one of these tickets - the more the merrier!
Instructions on setting up your local development environment can be found in the GitHub repo.
NOTE: When choosing an issue to work on, please check out the #contributing channel on our Gitter chat, and let everyone know what you are working on. This is important, as somebody else may have already done some work on the issue - in which case they would probably love to have your help!
The Hall of Fame members are the hardworking devs who have built The Odin Project into the site that you see before you now.
