 in the issue tracker, along with [bugs](https://github.com/astral-sh/ruff/issues?q=is%3Aissue+is%3Aopen+label%3Abug)

 that are ready for contributions.
 
+If you're looking for a place to start, we recommend implementing a new lint rule (see:
+[_Adding a new lint rule_](#example-adding-a-new-lint-rule), which will allow you to learn from and
+pattern-match against the examples in the existing codebase. Many lint rules are inspired by
+existing Python plugins, which can be used as a reference implementation.
+
+As a concrete example: consider taking on one of the rules from the [`flake8-pyi`](https://github.com/astral-sh/ruff/issues/848)
+plugin, and looking to the originating [Python source](https://github.com/PyCQA/flake8-pyi) for
+guidance.
