We should probably complete progress on the badge, or remove it.

Automated Best Practices Badge Reminder for Pillow

This is an automated reminder that your project "Pillow" does not currently have a "best practices" badge, and its badge entry has not been updated in a while.

Your best practices badge entry is at https://www.bestpractices.dev/en/projects/6331 and was last updated on 2023-02-03 14:49:03 UTC. It is currently at 99% (out of 100%).

We encourage you to keep making progress. Please visit your badge entry at https://www.bestpractices.dev/en/projects/6331 to complete the information and get your badge!

If you want to see only what you're missing, visit your badge entry, select the button near the top labelled "Expand all panels", and then select the button near the top labelled "Hide met or N/A criteria". If you have questions, or need help, please contact cii-badges-questions-owner@lists.coreinfrastructure.org or file an issue at https://github.com/coreinfrastructure/best-practices-badge/issues (click on "new issue").

We don't send reminders if you continue to update your badge entry, and we only send reminders approximately every 30-60 days. However, if you want to disable these reminder messages, edit your badge entry at https://www.bestpractices.dev/en/projects/6331#project_disabled_reminders to turn on "disable inactivity reminder". Be sure to edit the project entry, don't just display it, if you want to change whether or not you'll receive an inactivity reminder. We hope you'll instead keep working at it and eventually earn the badge.

Thank you for your time.
