## Questions

### Is Close Month safe to install?

AIR scanned this exact version of Close Month and flagged nothing. AIR's verdict: safe. The verdict is named by the content that was read, at commit a0fda662dd52, so it cannot drift onto a version nobody scanned. The full report is at https://airmarket.ai/security/close-month.
