 While pull requests from unaffiliated contributors are welcome, please note that due to significant community interest and limited review throughput, the core team's primary focus is on the issues which are currently [on the roadmap](https://github.com/orgs/ppy/projects/7/views/6). Reviewing PRs that fall outside of the scope of the roadmap is done on a best-effort basis, so please be aware that it may take a while before a core maintainer gets around to review your change.

-The [issue tracker](https://github.com/ppy/osu/issues) should provide plenty of issues to start with. We also have a [`good-first-issue`](https://github.com/ppy/osu/issues?q=is%3Aissue+is%3Aopen+label%3Agood-first-issue) label, although from experience it is not used very often, as it is relatively rare that we can spot an issue that will definitively be a good first issue for a new contributor regardless of their programming experience.
+The [issue tracker](https://github.com/ppy/osu/issues) should provide plenty of issues to start with. We also have a [`good first issue`](https://github.com/ppy/osu/issues?q=is%3Aissue+is%3Aopen+label%3A%22good+first+issue%22) label, although from experience it is not used very often, as it is relatively rare that we can spot an issue that will definitively be a good first issue for a new contributor regardless of their programming experience.

 In the case of simple issues, a direct PR is okay. However, if you decide to work on an existing issue which doesn't seem trivial, **please ask us first**. This way we can try to estimate if it is a good fit for you and provide the correct direction on how to address it. In addition, note that while we do not rule out external contributors from working on roadmapped issues, we will generally prefer to handle them ourselves unless they're not very time sensitive.
