TheUsing issue tracker page seems to describe how to use issue tracker for people who want to report a bug and how to help triage issue.

Seeing this is the developer's guide (aka contributing to Python guide), it would be great if there are sections dedicated for how to search for issues to start contributing.
Eventhe section about what each fields in the issue tracker mean, perhaps it can be moved outside of the "triaging" section. Those info are useful for general contributors too, not just for triagers. A first time contributor might decide to skip that section entirely, because they don't have triage role, and therefore missing out important information.
