Issues

Create issue

If no issue exists, create a new one. When writing, be sure to follow the template provided and to include a minimal, reproducible, example. Attach any relevant labels to the final issue once created.

Wait

A project maintainer will triage the issue and may ask for additional information. Please be patient as we manage a high volume of issues.

If you are adding an issue, please try to keep it focused on a single topic. If two issues are related, or blocking, please link them rather than combining them. For example,

This issue is blocked by #123 and related to #456.

Suggest features

Have an idea for a new feature or enhancement?

Search the issues for the respective repository for existing feature requests.

Discuss

If no requests exist, start a new discussion under the relevant category so that project maintainers and the community can provide feedback.

Describe

Be sure to describe the use case and why it would be valuable to others. If possible, provide examples or mockups where applicable.

Improve documentation

Documentation improvements are always welcome! We strive to keep our docs clear and comprehensive, and your perspective can make a big difference.
