Core maintainer of OpenProject here. We do welcome all outside contributions, but please note that while the application relies heavily on Ruby/Rails for backend, API and rendering, a large portion is also Angular/Typescript.

This will sometimes make it harder for developers to start working with OpenProject since for many topics, you will need both (e.g., API changes and frontend work). Especially so since the application has evolved for more than 10 years.

We recently did work on a "big picture" documentation for new developers to understand some of the concepts at play: https://docs.openproject.org/development/concepts/
