 For other activities, we will attempt to give some guidance on this page. If you're unsure of where to get started or how your skills matter to the project, _please reach out to us_! You can ask on the [mailing list](https://mail.python.org/mailman/listinfo/numpy-discussion) or [GitHub](http://github.com/numpy/numpy) (open an issue or comment on a relevant issue). These are our preferred communication channels (open source is open by nature!), however, if you prefer to discuss in private first, please reach out to our community coordinators at `[email protected]` or on [Slack](https://numpy-team.slack.com) (send an email to `[email protected]` for an invite the first time).
