+            This repository uses a bot to automatically label issues which have not had any activity (commit/comment/label) 
+            for 45 days. This helps us manage the community issues better. If the issue is still relevant, please add a comment to the 
+            issue so the bot can remove the label and we know it is still valid. If it is no longer relevant (or possibly fixed in the 
+            latest release), the bot will automatically close the issue in 14 days. Thank you for your contributions.
