+## Autoclose stale issues and PRs
+
+- After 30 days of no activity (no comments or commits on an issue/PR) we automatically tag it as "stale" and add a message: ```This issue/PR has gone 30 days without any activity and meets the project's definition of "stale". This will be auto-closed if there is no new activity over the next 60 days. If the issue is still relevant and active, you can simply comment with a "bump" to keep it open, or add the label "not_stale". Thanks for keeping our repository healthy!```
+- After 60 more days of no activity we automatically close the issue/PR.
