Contributing

Feel free to join the Discord above and join the thread for this list if you want to improve it! Alternatively, create a discussion if you want to discuss here on GitHub.

This document is a work in progress. Feel free to improve it by:

• Adding new, unique projects.
• Improving formatting.
• Updating statuses of projects that have been abandoned.

Please follow these guidelines when adding a project:

• Familiarize yourself with Markdown so you don't break things.
• This goes without saying, but it should be relevant to osu!.
  • It also should not break osu! rules (ex. tools that give advantages that interact with the client, custom servers, etc.) If you don't know, ask.
• Provide some (concise) details about your project.
• Avoid using link shorteners when possible.
  • These are hard to moderate and deal with, hard links are appreciated (ex. A clean Discord invite link, a website, or a Git page for your bot)
  • Long links can be dealt with by using reference style links. This helps people using the web editor to help readability.
  • If you link to another project in the description that is already on this page, use a reference style link as well.
• When using the GitHub web editor use No wrap option so it doesn't look terrible when editing long tables.
