We welcome all contributions, but keep in mind that we already have the full site designed (mock-ups). If you wish to work on a new section, please open a ticket and we will give you what you need from a design perspective to proceed. If you want to make changes to the design, we recommend you open an issue with your intentions before spending too much time, to ensure no effort is wasted.

If you wish to help with localisation efforts, head over to crowdin. If you're unsure of what you can help with, check out the list of open issues. (especially those with the "good first issue" label).

Please see CONTRIBUTING.md for information about the code standards we expect from pull requests.

While we have standards in place, nothing is set in stone. If you have an issue with the way code is structured; with any libraries we are using; with any processes involved with contributing, please bring it up. We welcome all feedback so we can make contributing to this project as pain-free as possible.

For those interested, we love to reward quality contributions via bounties, paid out via paypal or osu! supporter tags. Don't hesitate to request a bounty for your work on this project.

If you need help with anything, you have two options:

If you have something you want to discuss in detail, or have hit an issue which you believe others will also have in deployment or development of the system, opening an issue is the best way to get help. It creates a permanent resource for others wishing to contribute to conversation. Please make sure to search first in case someone else has already addressed the same issue!

Alternatively, you can join the development discord for assistance.
